Hi @Paul. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To customize the dropdown menu for the "Events" item in the Nuxt UI NavigationMenu so that it floats below the icon and does not take up the full width, you should use the ui prop to target the dropdown content specifically. The Nuxt UI NavigationMenu exposes a ui prop where you can override classes for different slots, including the dropdown/content area. For your use case, you want to: - Set a minimum width (e.g., min-w-48 or a custom width class). - Prevent the dropdown from taking the full width. - Adjust other CSS properties as needed. Here’s how you can do it:

<template>
  <UNavigationMenu
    :items="navigationItems"
    class="bg-nhblue-900 px-4"
    :ui="{
      // Override only the dropdown/content area
      content: 'min-w-48 w-auto left-0', // min width, auto width, align left
    }"
  >
    <template #item-leading="{ item }">
      <img v-if="item.img" :src="item.img" alt="" class="w-5 h-5 object-contain" />
      <UIcon v-else-if="item.icon" :name="item.icon" class="size-5" />
      <UAvatar v-else-if="item.avatar" v-bind="item.avatar" />
    </template>
  </UNavigationMenu>
</template>

<template>
  <UNavigationMenu
    :items="navigationItems"
    class="bg-nhblue-900 px-4"
    :ui="{
      // Override only the dropdown/content area
      content: 'min-w-48 w-auto left-0', // min width, auto width, align left
    }"
  >
    <template #item-leading="{ item }">
      <img v-if="item.img" :src="item.img" alt="" class="w-5 h-5 object-contain" />
      <UIcon v-else-if="item.icon" :name="item.icon" class="size-5" />
      <UAvatar v-else-if="item.avatar" v-bind="item.avatar" />
    </template>
  </UNavigationMenu>
</template>

- The content key in the ui prop lets you set Tailwind or custom classes for the dropdown.
- min-w-48 sets a minimum width, w-auto prevents it from stretching, and left-0 aligns it to the left of the trigger (you can adjust this as needed). If you want to target only the "Events" dropdown, you can use the ui property on the specific item in your navigationItems array:

const navigationItems = [
  // ...other items
  {
    label: 'Events',
    ui: {
      content: 'min-w-48 w-auto left-0', // Only affects Events dropdown
    },
    children: [
      { label: 'Upcoming' },
      { label: 'Prior' },
      { label: 'Make Event' }
    ]
  }
]

const navigationItems = [
  // ...other items
  {
    label: 'Events',
    ui: {
      content: 'min-w-48 w-auto left-0', // Only affects Events dropdown
    },
    children: [
      { label: 'Upcoming' },
      { label: 'Prior' },
      { label: 'Make Event' }
    ]
  }
]

This approach allows you to customize the dropdown for just the "Events" item without affecting others. You can add any additional classes for further styling as needed. References:

Let me check the knowledge base for you again. One moment! :books: ---------------------- You're correct—setting the ui.content class only affects the dropdown's content area, but the dropdown's viewport or container may still be taking up the full width. According to the Nuxt UI documentation, you should also override the viewport and possibly childList slots to control the dropdown's overall width and alignment. Here’s how you can restrict the dropdown width for the "Events" item:

const navigationItems = [
  // ...other items
  {
    label: 'Events',
    ui: {
      viewport: 'w-auto min-w-48',      // Controls the dropdown's outer container width
      content: 'w-auto min-w-48',       // Controls the dropdown's content area
      childList: 'w-auto min-w-48',     // Controls the list of child items
    },
    children: [
      { label: 'Upcoming' },
      { label: 'Prior' },
      { label: 'Make Event' }
    ]
  }
]

const navigationItems = [
  // ...other items
  {
    label: 'Events',
    ui: {
      viewport: 'w-auto min-w-48',      // Controls the dropdown's outer container width
      content: 'w-auto min-w-48',       // Controls the dropdown's content area
      childList: 'w-auto min-w-48',     // Controls the list of child items
    },
    children: [
      { label: 'Upcoming' },
      { label: 'Prior' },
      { label: 'Make Event' }
    ]
  }
]

Apply these classes to the ui property of the "Events" item. This should ensure that both the dropdown background and its content do not stretch to the full screen width, but instead use the minimum width you specify. This approach is based on the official documentation, which shows how to use the ui prop to target viewport, content, and childList for custom sizing and layout of dropdowns in the NavigationMenu component see here. If you need even more control, you can further adjust these classes or use custom CSS as needed. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai you are gonna find this funny, that did nothing, nothings changed. infact if i remove content it just goes back to default, so viewport and childlist did nothing

Let me check the knowledge base for you again. One moment! :books: ---------------------- Thank you for your feedback. Based on the official Nuxt UI documentation, the primary way to control the dropdown width in the UNavigationMenu is by using the content key in the ui prop. The documentation examples only show the use of content for controlling the width of the dropdown, and there is no explicit mention of viewport or childList affecting the dropdown width in the way you described for the NavigationMenu component. For example, the documentation provides this pattern:

<UNavigationMenu
  :items="items"
  :ui="{
    content: 'sm:w-auto',
    childList: 'sm:w-96',
    childLinkDescription: 'text-balance line-clamp-2'
  }"
  class="w-full justify-center"
>
  <!-- ... -->
</UNavigationMenu>

<UNavigationMenu
  :items="items"
  :ui="{
    content: 'sm:w-auto',
    childList: 'sm:w-96',
    childLinkDescription: 'text-balance line-clamp-2'
  }"
  class="w-full justify-center"
>
  <!-- ... -->
</UNavigationMenu>

In this example, the content and childList classes are used, but the main control for the dropdown width is through the content class. There is no evidence in the documentation that viewport will affect the dropdown width for the NavigationMenu. If removing content returns the dropdown to its default behavior, this matches the documented approach NavigationMenu with content slot. If the dropdown background is still taking the full width of the page, the knowledge sources do not provide further details or alternative props to control this behavior. The documentation does not mention a direct way to scope the dropdown background width beyond the content class. Summary:
- The only documented way to control the dropdown width is via the content key in the ui prop. - There is no mention in the knowledge sources of viewport or childList affecting the dropdown width for NavigationMenu. - If this does not achieve the desired effect, the knowledge sources do not provide additional solutions. If you need more advanced control, you may need to use custom CSS targeting the generated classes, but this is not covered in the official documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
