Extending Nuxt UI components etc

So specifically i want to extend the provideDashboardContext from DashboardGroup. My app shell has one main sidebar that's always collapsed to icons only state, a top navigation bar, and a contextual sidebar (via dashboardpanel) that is togglable and i feel like the dashboard context would be the right entry point to start tweaking so they are aware of each other's state as needed and can do the yes do x (that's already supported) but also do y (additional custom action) type of thing.. what would be right way to go about this.. i found https://gist.github.com/lordzouga/866c515f27e9b0eb3bc8d47842afd44c as an example to extend a nuxt-ui template but would appreciate - confirmation that the approach makes sense - the recommended way to do this

Hi @SamKaizen. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Your approach—extending the dashboard context to coordinate state between multiple dashboard components—makes sense conceptually, especially for advanced layouts where components need to be aware of each other's state. However, based on the provided knowledge sources, there is no explicit documentation or example for directly extending or customizing the internal provideDashboardContext from the Nuxt UI Pro DashboardGroup component. What the Knowledge Sources Say - DashboardGroup is the main layout wrapper for dashboard components and manages sidebar state, persistence, and sizing. It provides context for its child components, but the sources do not detail how to extend or override the context it provides, nor do they expose the internal provideDashboardContext API for user extension or injection. The documented API focuses on props and slots for layout and persistence, not for context extension or custom actions between components [DashboardGroup]. - The sources do not mention a recommended or supported way to hook into or extend the context provided by DashboardGroup, nor do they describe a pattern for injecting additional custom actions into the dashboard context. - The example you referenced (the gist) is not part of the official documentation, and there is no official guidance in the sources about extending Nuxt UI templates or context in this way. What You Can Do - You can use the documented props, slots, and theming options to customize the behavior and appearance of dashboard components. - For advanced state sharing or custom actions, you may need to implement your own composable or provide/inject pattern outside of the built-in DashboardGroup context, as the official sources do not describe a way to extend the internal context directly. Summary - Your approach is logical for advanced use cases, but the official documentation does not confirm or recommend a way to extend provideDashboardContext or the internal context of DashboardGroup. - Recommended way: Use the documented props, slots, and theming for customization. For deeper state sharing, consider your own composable or provide/inject solution, as the official sources do not provide a built-in extension mechanism for the dashboard context. If you need to go beyond what is documented, you may need to explore the source code or reach out to the Nuxt UI Pro community for advanced patterns, as the knowledge sources do not explicitly cover this scenario.

I'm sorry, but the knowledge sources do not contain enough information to confirm or recommend a specific way to extend provideDashboardContext from DashboardGroup or to inject additional custom actions into the dashboard context. The official documentation focuses on props, slots, and theming for customization, not on context extension.

@kapa.ai i've been looking at the code internals and i noticed a thing in UDashboardSidebar, UDashboardSidebarToggle and UDashboardSidebarGroup -> they use hooks like

toggleSidebar: () => {
    nuxtApp.hooks.callHook('dashboard:sidebar:toggle')
  },

toggleSidebar: () => {
    nuxtApp.hooks.callHook('dashboard:sidebar:toggle')
  },

to communicate but none of these hooks are exposed so if we want the pattern like yes toggle sidebar but also do x then or have a different component say the primary UDashboardNavbar also listen to these events.. what is the suggested way.. even if no way is suggested via documentatio what would be the suggested nuxt3/vue way

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on your investigation of the code internals, you've identified that Nuxt UI Pro's dashboard components use Nuxt's event system (hooks) for internal communication. This is a good observation, and I can provide guidance on how to work with these hooks. Looking at the knowledge sources, we can see that Nuxt provides a powerful event system powered by the hookable library:

const nuxtApp = useNuxtApp()

// Listen to an event
nuxtApp.hook('dashboard:sidebar:toggle', () => {
  // Your custom logic here
})

// Emit an event
await nuxtApp.callHook('dashboard:sidebar:toggle')

const nuxtApp = useNuxtApp()

// Listen to an event
nuxtApp.hook('dashboard:sidebar:toggle', () => {
  // Your custom logic here
})

// Emit an event
await nuxtApp.callHook('dashboard:sidebar:toggle')

Since the dashboard components are using hooks like dashboard:sidebar:toggle internally, you can listen to these same hooks in your own components to react to sidebar state changes, even if they're not officially documented. Here's how you could approach this: 1. Listen to the internal hooks: In your custom components or plugins, you can use useNuxtApp() to access the Nuxt app instance and listen to these internal hooks:

const nuxtApp = useNuxtApp()

// Listen to the sidebar toggle event
nuxtApp.hook('dashboard:sidebar:toggle', () => {
  // Do your custom action here
  console.log('Sidebar was toggled')
  // Perform additional actions
})

const nuxtApp = useNuxtApp()

// Listen to the sidebar toggle event
nuxtApp.hook('dashboard:sidebar:toggle', () => {
  // Do your custom action here
  console.log('Sidebar was toggled')
  // Perform additional actions
})

2. Create your own hooks: You can also extend the system by creating your own hooks for additional functionality:

// In a plugin or component
const nuxtApp = useNuxtApp()

// Call your custom hook when needed
function handleSomething() {
  nuxtApp.callHook('my-app:sidebar:custom-action', { data: 'value' })
}

// Listen to your custom hook elsewhere
nuxtApp.hook('my-app:sidebar:custom-action', (payload) => {
  console.log('Custom action triggered with', payload)
})

// In a plugin or component
const nuxtApp = useNuxtApp()

// Call your custom hook when needed
function handleSomething() {
  nuxtApp.callHook('my-app:sidebar:custom-action', { data: 'value' })
}

// Listen to your custom hook elsewhere
nuxtApp.hook('my-app:sidebar:custom-action', (payload) => {
  console.log('Custom action triggered with', payload)
})

This approach follows the Nuxt events pattern described in the Events documentation, which mentions that "Events can have multiple listeners that do not depend on each other." For type safety, you might want to augment the types as mentioned in the documentation:

declare module '#app' {
  interface RuntimeNuxtHooks {
    'dashboard:sidebar:toggle': () => void
    'my-app:sidebar:custom-action': (payload: any) => void
  }
}

declare module '#app' {
  interface RuntimeNuxtHooks {
    'dashboard:sidebar:toggle': () => void
    'my-app:sidebar:custom-action': (payload: any) => void
  }
}

This approach allows you to both listen to the internal dashboard component events and extend the system with your own events, creating a decoupled communication system between your components without directly modifying the Nuxt UI Pro components. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai so u r saying if i want the existing nuxt-ui components to do something extra even for events they currently listen to I should either extend them or wrap them into another component and manage the extra functionality there while also listening to the event? but with the wrapper component approach there's no timing guarantee that the wrapped component would have completed its even handling at that point?

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- You've raised an excellent point about timing guarantees when working with Nuxt UI Pro's dashboard components and their internal event system. Based on the knowledge sources, there are two main approaches you could take: 1. Listening to the same events When you listen to the same events that the Nuxt UI components use internally (like dashboard:sidebar:toggle), there's indeed no guarantee about execution order. The Nuxt event system documentation states:

Events can have multiple listeners that do not depend on each other.

This means your listener might execute before, after, or concurrently with the component's internal listener, which could lead to race conditions or unexpected behavior. 2. Extending or wrapping components You have two options here: Extending components: This would involve creating your own version of the component that inherits from the original but adds your custom functionality. This approach gives you more control over the timing of events. Wrapper components: You could create a wrapper component that renders the Nuxt UI component but adds your own event listeners. This is simpler but has the timing issue you mentioned. A third approach: Two-way communication The Nuxt events documentation mentions a pattern that might help:

const nuxtApp = useNuxtApp()

nuxtApp.hook('app:user:registered', payload => {
  payload.message = 'Welcome to our app!'
})

const payload = {
  id: 1,
  name: 'John Doe',
}

await nuxtApp.callHook('app:user:registered', payload)
// payload.message will be 'Welcome to our app!'

const nuxtApp = useNuxtApp()

nuxtApp.hook('app:user:registered', payload => {
  payload.message = 'Welcome to our app!'
})

const payload = {
  id: 1,
  name: 'John Doe',
}

await nuxtApp.callHook('app:user:registered', payload)
// payload.message will be 'Welcome to our app!'

This shows that you can modify the payload object to enable two-way communication between the emitter and listeners. If the Nuxt UI components pass a mutable payload object when calling hooks, you could potentially use this pattern to influence their behavior. Recommendation Given these considerations, I would recommend: 1. First try listening to the existing events and see if the timing works for your use case 2. If timing issues arise, consider creating wrapper components that: - Listen for the original events - Implement your custom logic - Then programmatically trigger the same actions on the wrapped components For example, you could intercept the toggle action, do your custom work, and then manually toggle the sidebar using the component's API (if available) or by dispatching the same event. The Nuxt hooks system is powerful but doesn't provide execution order guarantees, so you'll need to design your solution with this limitation in mind. I hope this helps clarify the approaches you could take! ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai intercept an event? tell me more 👀 coz i thought u couldn't do that without extending the components themselves?

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- You're right to question this - I should clarify what I meant by "intercepting" events in the Nuxt hooks system, as the knowledge sources don't show a way to truly intercept and prevent the original event handlers from executing. Based on the Nuxt documentation about hooks and events, there's no built-in mechanism to intercept hooks in the sense of stopping their propagation or preventing other listeners from executing. The Nuxt event system (powered by unjs/hookable) doesn't provide an event cancellation mechanism like event.preventDefault() in DOM events. What you can do instead: 1. Listen to events - You can add your own listeners to the same hooks that Nuxt UI components use:

const nuxtApp = useNuxtApp()
nuxtApp.hook('dashboard:sidebar:toggle', () => {
  // Your code runs when the event is triggered
  // But the original handler will still run too
})

const nuxtApp = useNuxtApp()
nuxtApp.hook('dashboard:sidebar:toggle', () => {
  // Your code runs when the event is triggered
  // But the original handler will still run too
})

2. Use the runtime hook composable - For component-scoped hooks that clean up automatically:

// In a component
useRuntimeHook('dashboard:sidebar:toggle', () => {
  // Your code here
})

// In a component
useRuntimeHook('dashboard:sidebar:toggle', () => {
  // Your code here
})

As mentioned in the useRuntimeHook documentation, this will automatically unregister when the component is unmounted. 3. Modify shared state - You can use the payload object to influence behavior if the components check this state:

nuxtApp.hook('dashboard:sidebar:toggle', (payload) => {
  // Modify payload if the component uses it for decisions
  payload.someFlag = true
})

nuxtApp.hook('dashboard:sidebar:toggle', (payload) => {
  // Modify payload if the component uses it for decisions
  payload.someFlag = true
})

But you're correct - to truly intercept and prevent the original behavior, you would need to extend the components themselves or create wrapper components that don't pass through the original events but instead implement their own logic. The Nuxt hooks system is designed for notification and coordination rather than interception and prevention, which is an important distinction when planning your architecture. Does that clarify the limitations of the hooks system for your use case? ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai mmm seems like i'm looking at extending the base components and the default DashboardContext then :| slightly painful but perhaps better considering the forward maintainability?

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on your assessment, extending the base components and the DashboardContext does seem like the most reliable approach for your custom dashboard requirements, even if it requires more upfront work. Looking at the knowledge sources, Nuxt provides a layers system that's well-suited for extending components:

// base/nuxt.config.ts
export default defineNuxtConfig({
  // Extending from base nuxt.config.ts!
})

// base/nuxt.config.ts
export default defineNuxtConfig({
  // Extending from base nuxt.config.ts!
})

This layers approach would allow you to create extended versions of the dashboard components while maintaining forward compatibility with future updates to Nuxt UI Pro. As mentioned in the Authoring Nuxt Layers documentation, you can extend components by placing them in a components/ directory within your layer. For your specific case with the dashboard components, you could: 1. Create extended versions of UDashboardGroup, UDashboardSidebar, and other components 2. Implement your own enhanced version of the dashboard context with additional state and methods 3. Use the same hook names for compatibility, but add your own custom hooks for the additional functionality This approach gives you complete control over the timing of events and state changes, which addresses the concerns you raised about event handling order. While it is more work initially, it provides several benefits: - Full control over component behavior - Predictable event handling - Clear separation between original and custom functionality - Better maintainability as Nuxt UI Pro evolves The layer-based approach also means you can gradually migrate to newer versions of Nuxt UI Pro by updating your base layer, while keeping your extensions separate and maintainable. Would you like more specific guidance on setting up a layer for extending these dashboard components? ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai a question in reference to nuxt events.. say we have a custom event defined by our custom version of UDashboardPanel

const nuxtApp = useNuxtApp()

// Listen to an event
nuxtApp.hook('dashboard:panel:minimise', () => {
  // Your custom logic here
})

const nuxtApp = useNuxtApp()

// Listen to an event
nuxtApp.hook('dashboard:panel:minimise', () => {
  // Your custom logic here
})

calling this hook via callhook is a documented pattern.. if we wanted the custom UDashboardNavbar to also listen to it.. would we need to use the exact same code there too? with the same 1st argument?

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Yes, to have your custom UDashboardNavbar component listen to the same 'dashboard:panel:minimise' event, you would use the same hook pattern with the exact same event name as the first argument. This is how Nuxt's event system works - multiple components can listen to the same event. Here's how you would implement it in your custom UDashboardNavbar component:

const nuxtApp = useNuxtApp()

// Listen to the same event in UDashboardNavbar
nuxtApp.hook('dashboard:panel:minimise', () => {
  // Custom logic for the navbar when panel is minimized
  // For example, adjust navbar width or show/hide certain elements
})

const nuxtApp = useNuxtApp()

// Listen to the same event in UDashboardNavbar
nuxtApp.hook('dashboard:panel:minimise', () => {
  // Custom logic for the navbar when panel is minimized
  // For example, adjust navbar width or show/hide certain elements
})

This approach follows Nuxt's event system pattern as described in the Events documentation, which states:

Events can have multiple listeners that do not depend on each other.

If you're implementing this in a component, you might want to use the useRuntimeHook composable instead, which will automatically clean up the listener when the component is unmounted:

// In your custom UDashboardNavbar component
useRuntimeHook('dashboard:panel:minimise', () => {
  // Your navbar-specific logic here
})

// In your custom UDashboardNavbar component
useRuntimeHook('dashboard:panel:minimise', () => {
  // Your navbar-specific logic here
})

This approach is documented in the useRuntimeHook documentation and is available in Nuxt v3.14+. The key point is that the first argument must be identical across all components that need to listen to the same event. This is how Nuxt's event system identifies which event to trigger. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai i sort of understand extending a ui component through options extend way when it's the functionality that is the issue not the template.. if we wanted to add an extra slot how would we go about doing that?specifically consider the UDashboardPanel component

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the knowledge sources, to add an extra slot to the UDashboardPanel component, you would need to create your own extended version of the component. Let's look at how you could approach this specifically for UDashboardPanel. The UDashboardPanel component currently has these slots as documented:

Slots
| Slot | Type |
|---|---|
| `default` | `{}` |
| `header` | `{}` |
| `body` | `{}` |
| `footer` | `{}` |
| `resize-handle` | `{ onMouseDown: (e: MouseEvent) => void; onTouchStart: (e: TouchEvent) => void; }` |

Slots
| Slot | Type |
|---|---|
| `default` | `{}` |
| `header` | `{}` |
| `body` | `{}` |
| `footer` | `{}` |
| `resize-handle` | `{ onMouseDown: (e: MouseEvent) => void; onTouchStart: (e: TouchEvent) => void; }` |

To add a new slot (let's say a sidebar slot), you would need to: 1. Create a new component that extends UDashboardPanel 2. Add your new slot to the template Here's how you could implement this:

<!-- components/MyDashboardPanel.vue -->
<template>
  <UDashboardPanel 
    :id="id" 
    :min-size="minSize" 
    :max-size="maxSize" 
    :default-size="defaultSize" 
    :resizable="resizable"
    :ui="ui"
  >
    <template #header v-if="$slots.header">
      <slot name="header" />
    </template>
    
    <template #body v-if="$slots.body">
      <slot name="body" />
    </template>
    
    <template #footer v-if="$slots.footer">
      <slot name="footer" />
    </template>
    
    <template #resize-handle="slotProps" v-if="$slots['resize-handle']">
      <slot name="resize-handle" v-bind="slotProps" />
    </template>
    
    <!-- Your new custom slot -->
    <template #sidebar v-if="$slots.sidebar">
      <slot name="sidebar" />
    </template>
    
    <template #default v-if="$slots.default">
      <slot />
    </template>
  </UDashboardPanel>
</template>
<script setup>
defineProps({
  id: {
    type: String,
    default: () => useId()
  },
  minSize: {
    type: Number,
    default: 15
  },
  maxSize: {
    type: Number,
    default: 100
  },
  defaultSize: {
    type: Number,
    default: 0
  },
  resizable: {
    type: Boolean,
    default: false
  },
  ui: {
    type: Object,
    default: () => ({})
  }
})
</script>

<!-- components/MyDashboardPanel.vue -->
<template>
  <UDashboardPanel 
    :id="id" 
    :min-size="minSize" 
    :max-size="maxSize" 
    :default-size="defaultSize" 
    :resizable="resizable"
    :ui="ui"
  >
    <template #header v-if="$slots.header">
      <slot name="header" />
    </template>
    
    <template #body v-if="$slots.body">
      <slot name="body" />
    </template>
    
    <template #footer v-if="$slots.footer">
      <slot name="footer" />
    </template>
    
    <template #resize-handle="slotProps" v-if="$slots['resize-handle']">
      <slot name="resize-handle" v-bind="slotProps" />
    </template>
    
    <!-- Your new custom slot -->
    <template #sidebar v-if="$slots.sidebar">
      <slot name="sidebar" />
    </template>
    
    <template #default v-if="$slots.default">
      <slot />
    </template>
  </UDashboardPanel>
</template>
<script setup>
defineProps({
  id: {
    type: String,
    default: () => useId()
  },
  minSize: {
    type: Number,
    default: 15
  },
  maxSize: {
    type: Number,
    default: 100
  },
  defaultSize: {
    type: Number,
    default: 0
  },
  resizable: {
    type: Boolean,
    default: false
  },
  ui: {
    type: Object,
    default: () => ({})
  }
})
</script>

However, this approach has a limitation: your new slot won't be positioned in the component's internal structure - it will just be passed through to the original UDashboardPanel component, which doesn't know how to handle it. For a more complete solution where you can actually position the new slot within the component's structure, you would need to copy and modify the original component's template. This is more involved but gives you full control: 1. Look at the source code of UDashboardPanel 2. Create a new component with a similar structure 3. Add your new slot where you want it to appear Since the knowledge sources don't provide the full template of UDashboardPanel, you would need to check the GitHub repository to see the component's internal structure. After creating your extended component, you would use it in your application instead of the original UDashboardPanel:

<template>
  <MyDashboardPanel>
    <template #header>
      <UDashboardNavbar title="Dashboard" />
    </template>
    
    <template #sidebar>
      <!-- Your sidebar content here -->
    </template>
    
    <template #body>
      <!-- Your main content here -->
    </template>
  </MyDashboardPanel>
</template>

<template>
  <MyDashboardPanel>
    <template #header>
      <UDashboardNavbar title="Dashboard" />
    </template>
    
    <template #sidebar>
      <!-- Your sidebar content here -->
    </template>
    
    <template #body>
      <!-- Your main content here -->
    </template>
  </MyDashboardPanel>
</template>

This approach gives you the flexibility to add new slots while maintaining compatibility with the original component's API. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai since the original won't know how to handle it isn't that a pretty useless solution :P so the options seem to be - copy over the original component from muxt-ui-pro repos and adjust/expand as needed - see if u can reutilise the header or body slots with some additional styling/structure specifically i need to include something like a DashboardPanelToggle button in the panel that'd minimise (hide) the panel so adjusting the header slot to always show the button on the right while still leaving the rest of the slot free for adding a navbar or whatever might work?

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- You're absolutely correct: simply adding a new slot to a wrapper component around UDashboardPanel is not effective, since the original component won't render or position that slot—so it’s not a practical solution. Based on the knowledge sources, your two options are: 1. Copy and modify the original component:
You can copy the source of UDashboardPanel from the Nuxt UI Pro repository, then add your custom slot or UI logic where you need it. This gives you full control over the structure and slot placement, but you’ll need to maintain your custom version as the library updates. 2. Leverage existing slots (like header) and enhance them:
The header slot is designed for customization. You can use it to inject both your custom button (such as a DashboardPanelToggle to minimize/hide the panel) and any other content (like a navbar). For example, you can structure your slot content so the toggle button is always on the right, and the rest of the slot is available for other elements:

   <template #header>
     <div class="flex items-center justify-between w-full">
       <div>
         <!-- Left side: your navbar or other content -->
         <UDashboardNavbar title="Dashboard" />
       </div>
       <div>
         <!-- Right side: your custom toggle button -->
         <DashboardPanelToggle @click="minimizePanel" />
       </div>
     </div>
   </template>

   <template #header>
     <div class="flex items-center justify-between w-full">
       <div>
         <!-- Left side: your navbar or other content -->
         <UDashboardNavbar title="Dashboard" />
       </div>
       <div>
         <!-- Right side: your custom toggle button -->
         <DashboardPanelToggle @click="minimizePanel" />
       </div>
     </div>
   </template>

This approach is recommended by the documentation, which shows using the header slot to inject custom content, such as a navbar or buttons [DashboardPanel usage]. Summary:
- Wrapping and adding a new slot is not effective unless the base component is modified to render it. - The recommended and maintainable approach is to use the header slot and structure your content (with flex, grid, etc.) to include both your custom button and any other elements you need. - If you need more control than the slots provide, copying and modifying the component is the only way, but it comes with maintenance overhead. This matches the patterns shown in the official documentation and is the best-supported way to achieve your goal with the current Nuxt UI Pro components. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

One moment! :books: ---------------------- The line @click="collapseSidebar?.(!sidebarCollapsed)" in the UDashboardSidebarCollapse component attaches a click event handler to the underlying button. When the button is clicked, it calls the collapseSidebar function (if it exists), passing the opposite of the current sidebarCollapsed state as an argument. This effectively toggles the collapsed state of the sidebar: if the sidebar is currently collapsed, it will expand, and if it is expanded, it will collapse. This pattern is used to control the collapsed state of the sidebar from the collapse button, as described in the documentation for UDashboardSidebarCollapse and its usage within the sidebar header or navbar slots [DashboardSidebarCollapse usage]. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai i could not understand the difference between content and default slots of UDashboardSidebar there are examples and explanation for default but content slot is less clear

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- The knowledge sources provide clear examples and explanations for the default slot of UDashboardSidebar, showing it is used to customize the main content area of the sidebar—typically where you place navigation menus, buttons, or other sidebar content [DashboardSidebar usage]. However, the content slot is listed in the slot table but is not explained or demonstrated in the examples. The documentation does not clarify its intended use or how it differs from the default slot [DashboardSidebar slots]. I'm sorry, but the knowledge sources do not explicitly describe the purpose or usage of the content slot in UDashboardSidebar, so I cannot provide a confident answer about its difference from the default slot. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

can u give some clarity

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the provided code snippet and the knowledge sources, here’s some clarity on the difference between the default and content slots in UDashboardSidebar: - The content slot is used to override the entire internal structure of the sidebar menu. If you provide a content slot, it replaces the default rendering logic inside the sidebar menu. This means you can fully customize the header, body, and footer areas as you wish. - The default slot, on the other hand, is typically used for the main content area of the sidebar (the body), and is rendered inside the default structure provided by the component. From the code you shared, you can see that the content slot wraps the entire menu structure, including the header, body (which contains the default slot), and footer. If you provide a content slot, you can customize all these areas. If you do not provide a content slot, the component falls back to its default structure, using the header, default, and footer slots as appropriate. This pattern is hinted at in the documentation, which states:

Use the body slot to fill the menu body (under the header) or the content slot to fill the entire menu [DashboardSidebar mode].

So, in summary: - content slot: Overrides the entire menu structure—use this for full customization. - default slot: Used for the main content area (body) within the default menu structure. If you only want to customize the main area, use the default slot. If you want to take over the whole menu rendering, use the content slot. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai so using content we could create additional slots from scratch? like left right (for a 2 col hypothetical variant)?

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Yes, based on the code snippet and the documentation, using the content slot in UDashboardSidebar allows you to fully override the internal menu structure. This means you can create your own custom layout inside the sidebar, including adding new areas or slots such as left and right for a two-column variant. The content slot gives you complete control over what is rendered, so you are not limited to the default header, body, and footer structure [DashboardSidebar mode]. However, the knowledge sources do not provide explicit examples of implementing additional named slots (like left or right) within the content slot. They do confirm that the content slot is intended for full customization of the sidebar menu, so you can structure it as needed for your use case. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai would it also remove the toggle and resize-handle slots?

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- If you use the content slot in UDashboardSidebar, it will override the entire internal menu structure, including the default placement of the toggle and resize-handle slots. This means that the default toggle and resize-handle elements provided by the component will not be rendered unless you explicitly include similar functionality within your custom content slot structure. The documentation states:

Use the body slot to fill the menu body (under the header) or the content slot to fill the entire menu [DashboardSidebar mode].

However, the knowledge sources do not explicitly mention the behavior of the toggle and resize-handle slots when the content slot is used. Based on the provided code and documentation, it is implied that providing a content slot replaces the default structure, so those slots would not be rendered automatically. If you need toggle or resize-handle functionality in your custom layout, you would need to implement or include them manually within your custom content slot. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai actually isn't it more likely this is the logic for mobile version of sidebar?

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Yes, you are correct. The code snippet you provided is indeed related to the mobile version of the sidebar. In the Nuxt UI Pro documentation, it is mentioned that the content slot (and the associated menu logic) is used to fill the entire menu, which is particularly relevant for the mobile (or small screen) version of the sidebar. On desktop, the sidebar is typically always visible, while on mobile, it is rendered as a menu or drawer that can be toggled open or closed. The presence of logic for toggling and the use of the Menu component in your snippet further support this interpretation [DashboardSidebar mode]. So, the structure you see—where the content slot can override the entire menu—is primarily designed for the mobile sidebar experience. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai in UDasshboardNavbar i see a lot f cases like this ; <slot name="toggle" v-bind="dashboardContext"> given that the navbar isn't really doing anything with the group etc.. or saving size etc in cookie etc.. what exactly does this change

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- In UDashboardNavbar, when you see <slot name="toggle" v-bind="dashboardContext">, it means that the slot is being provided with the current dashboardContext as its slot props. This allows any component or template using the toggle slot to access properties and methods from the dashboardContext—such as sidebar state, toggle functions, or other context shared by the dashboard group. Even though the navbar itself does not manage things like sidebar size, persistence, or storage (those are handled by UDashboardGroup), passing dashboardContext to the slot enables components rendered in the toggle slot (like a custom toggle button) to interact with the dashboard context. For example, a custom toggle button in the navbar could use the context to open or close the sidebar, or react to its state. This pattern is a way to expose the dashboard context to slot content, making the navbar more flexible and allowing for advanced integrations without the navbar itself needing to manage or be aware of the underlying logic [DashboardNavbar documentation]. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai can u explain more i didn't entirely grok this

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Certainly! In UDashboardNavbar, when you see code like:

<slot name="toggle" v-bind="dashboardContext">

<slot name="toggle" v-bind="dashboardContext">

it means that when you use the toggle slot, you are given access to the dashboardContext object as slot props. This dashboardContext contains information and methods related to the overall dashboard state—such as whether the sidebar is open or collapsed, and functions to toggle or collapse it. Why is this useful?
Even though the navbar itself doesn't manage the sidebar or save its state, by passing dashboardContext to the slot, any custom component you put in the toggle slot can interact with the dashboard's state. For example, you could add a custom button in the navbar that uses dashboardContext to open or close the sidebar, or to check if the sidebar is currently collapsed. In summary:
- The navbar exposes the dashboard context to slot content. - This allows your custom slot content (like a toggle button) to interact with the dashboard's state, even though the navbar itself doesn't manage that state. - It makes the navbar more flexible and powerful for advanced use cases [DashboardNavbar documentation]. If you need a concrete example or further clarification, let me know! ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai 1. let's say we have a button in navbar left slot that should minimise a panel, we have extended dashboardcontext to have function signatures like togglePanel and state like panelExpanded what would need to be done at the UDashboardNavBar level then? how would the button get access to the expanded context? it wouldn't automatically rt? and if we have to create a UDashboardPanelCollapse anyway why can't we directly use the expanded context there itself?

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- You're correct in your thinking: the UDashboardNavbar itself does not automatically have access to your extended dashboard context unless you explicitly provide it. By default, the navbar only exposes what is passed to it via slot props, such as dashboardContext if the parent DashboardGroup or your custom context provider makes it available [DashboardNavbar documentation]. If you have extended the dashboard context to include functions like togglePanel and state like panelExpanded, you need to ensure that this extended context is provided to the navbar and its slots. This is typically done by: 1. Providing the extended context at a higher level (e.g., in your custom DashboardGroup or a composable). 2. Passing the context down to UDashboardNavbar via slot props, as shown in the documentation with v-bind="dashboardContext". For your button in the navbar's left slot to access and use togglePanel or panelExpanded, it must receive the extended context as slot props. Here’s how it would look:

<UDashboardNavbar>
  <template #left="{ togglePanel, panelExpanded }">
    <UButton @click="togglePanel(!panelExpanded)">
      Minimize Panel
    </UButton>
  </template>
</UDashboardNavbar>

<UDashboardNavbar>
  <template #left="{ togglePanel, panelExpanded }">
    <UButton @click="togglePanel(!panelExpanded)">
      Minimize Panel
    </UButton>
  </template>
</UDashboardNavbar>

This only works if the parent component (e.g., your custom DashboardGroup) is providing the extended context and the navbar is passing it to its slots. To your second point:
If you are creating a UDashboardPanelCollapse component, you can indeed use the expanded context directly within that component, especially if it is rendered inside the context provider. The main reason to expose the context to the navbar is if you want controls (like a minimize button) to be accessible from the navbar itself, not just from within the panel. Summary:
- The navbar does not automatically get the extended context; you must provide it via slot props. - If you want a button in the navbar to control the panel, ensure the context is passed down and used in the slot. - If you only need the control inside the panel, you can use the context directly there without involving the navbar. The knowledge sources confirm the slot prop pattern but do not provide a built-in mechanism for automatic context extension or propagation beyond what you explicitly provide [DashboardNavbar documentation]. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai hmmmm assuming the expanded context has been provided to the overridden/extended/custom UDashboardGroup does that mean all components like navbar dashboardpanel etc will now automatically get full expanded context?

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- If you have provided an expanded or custom dashboard context in your overridden/extended UDashboardGroup, the knowledge sources do not explicitly state that all child components like UDashboardNavbar, UDashboardPanel, etc., will automatically receive the full expanded context. The official documentation shows that context (such as dashboardContext) is passed to slots via v-bind, for example in UDashboardNavbar:

<slot name="toggle" v-bind="dashboardContext">

<slot name="toggle" v-bind="dashboardContext">

This means that for a component or slot to access the expanded context, it must be explicitly passed down—typically via slot props or by using Vue’s provide/inject mechanism. The documentation does not confirm that simply extending the context at the DashboardGroup level will automatically make it available to all child components without additional wiring [DashboardNavbar documentation]. In summary:
- The knowledge sources do not confirm that all components will automatically get the expanded context. - You will likely need to ensure the context is properly provided and injected, or passed as slot props, to each component that needs it. If you need all dashboard components to access the expanded context, you should verify that your context is being provided at a high enough level and that each component is set up to inject or receive it as needed. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai given that the useDashboard is directly used i thinkthe assumption should be that it won't and we should explicitly use it as needed

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- You are correct in your assumption. Based on the knowledge sources, the pattern in Nuxt UI Pro is that composables like useDashboard are used directly within components that need access to the dashboard context. This means the context is not automatically injected into all child components—each component must explicitly call the composable or receive the context via slot props or injection as needed. The documentation and code patterns show that context (such as dashboardContext) is passed explicitly, for example via slot props in components like UDashboardNavbar:

<slot name="toggle" v-bind="dashboardContext">

<slot name="toggle" v-bind="dashboardContext">

This reinforces the idea that you should explicitly use or provide the context where it is needed, rather than assuming it will be available everywhere by default [DashboardNavbar documentation]. So, your approach—to explicitly use the composable or context as needed in each component—is correct and aligns with the documented and intended usage. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

 <UDashboardNavbar
    id="top-navbar"

    icon="i-lucide-house"
  >

browser console is complaining abt extraneous prop id

kapa.ai•3mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- The knowledge sources do not explicitly mention support for an id prop on the UDashboardNavbar component. The documented props for UDashboardNavbar are: - as - icon - title - toggle - toggleSide - ui There is no mention of an id prop in the official documentation or API tables [DashboardNavbar documentation]. This is why passing id="top-navbar" results in a browser console warning about an extraneous prop. If you need to add an id to the rendered HTML element, you would need to either: - Extend the component to support the id prop, or - Use a wrapper element around UDashboardNavbar and assign the id to that wrapper. This limitation is due to the component's current API, not a general HTML restriction. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

That sounds like a solid approach. Extending provideDashboardContext is indeed the right way if you want to share state between DashboardGroup, DashboardPanel, and custom UI components (like your top nav and persistent sidebar). The idea is to wrap your layout in a custom context provider (like in the gist you shared), so you can inject and react to shared state — such as which panels are open, collapsed, or triggering custom actions. Recommended steps: Create a wrapper component (e.g. CustomDashboardGroup.vue) that uses provideDashboardContext() and extends the returned state with your custom logic (refs, computed, methods). Use <slot /> to wrap your actual layout (sidebar, navbar, panel). In child components, call useDashboardContext() to access or mutate state. Optional but useful: If you're using Nuxt UI Pro, you can even pass your custom context down to Nuxt UI Pro panels, and they’ll still work correctly. Let me know if you'd like an example that fits your layout structure — happy to help!
