Hi @Buu. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To change the background color of the Nuxt UI NavigationMenu, you can use Tailwind CSS utility classes directly on the component via the class prop. For example, to set a custom background color, add a Tailwind background class like bg-primary, bg-white, or any other color class to the UNavigationMenu:

<template>
  <UNavigationMenu
    :items="items"
    class="bg-primary" <!-- Change this to your desired Tailwind background class -->
  />
</template>

<template>
  <UNavigationMenu
    :items="items"
    class="bg-primary" <!-- Change this to your desired Tailwind background class -->
  />
</template>

You can replace bg-primary with any Tailwind color class that matches your design needs (e.g., bg-gray-100, bg-white, bg-blue-500, etc.). If you want more advanced customization (such as changing the background only for certain variants or states), you may need to override the component's theme using the new theming system in your app.config.ts. However, for most use cases, applying a Tailwind class via the class prop is sufficient and recommended by the documentation NavigationMenu Variant. If you need to target specific slots or elements inside the NavigationMenu, you would need to refer to the component's theme configuration, but the knowledge sources do not provide explicit details for background slot overrides. Summary:
Add your desired Tailwind background class to the class prop of UNavigationMenu to change its background color. If you need more granular control and the above does not meet your needs, please provide more details about which part of the NavigationMenu you want to style. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I want change background color when active or hover on item

Let me check the knowledge base for you again. One moment! :books: ---------------------- To change the background color of a NavigationMenu item when it is active or hovered, you should use the theme customization options provided by Nuxt UI. According to the documentation, you can control the classes applied to active and hovered items through the theme system or by using Tailwind utility classes in your configuration. For the default behavior, the theme applies classes like hover:bg-elevated/50 for hover and bg-elevated for active states on child links. For example: - Active child link:
bg-elevated text-highlighted - Hovered child link:
hover:bg-elevated/50 text-default hover:text-highlighted If you want to customize these, you can override the theme in your app.config.ts or use the class prop on your items. Here’s an example of how the theme handles these states:

active: {
  true: {
    childLink: 'bg-elevated text-highlighted',
    childLinkIcon: 'text-default'
  },
  false: {
    childLink: [
      'hover:bg-elevated/50 text-default hover:text-highlighted',
      'transition-colors'
    ],
    childLinkIcon: [
      'text-dimmed group-hover:text-default',
      'transition-colors'
    ]
  }
}

active: {
  true: {
    childLink: 'bg-elevated text-highlighted',
    childLinkIcon: 'text-default'
  },
  false: {
    childLink: [
      'hover:bg-elevated/50 text-default hover:text-highlighted',
      'transition-colors'
    ],
    childLinkIcon: [
      'text-dimmed group-hover:text-default',
      'transition-colors'
    ]
  }
}

To apply your own background color, you can override these classes. For example, to use a blue background on hover and active:

active: {
  true: {
    childLink: 'bg-blue-500 text-white',
    childLinkIcon: 'text-white'
  },
  false: {
    childLink: [
      'hover:bg-blue-100 text-default hover:text-blue-700',
      'transition-colors'
    ],
    childLinkIcon: [
      'text-dimmed group-hover:text-blue-500',
      'transition-colors'
    ]
  }
}

active: {
  true: {
    childLink: 'bg-blue-500 text-white',
    childLinkIcon: 'text-white'
  },
  false: {
    childLink: [
      'hover:bg-blue-100 text-default hover:text-blue-700',
      'transition-colors'
    ],
    childLinkIcon: [
      'text-dimmed group-hover:text-blue-500',
      'transition-colors'
    ]
  }
}

You would place this override in your app.config.ts under the Nuxt UI theme configuration for NavigationMenu as described in the documentation.
For more details and examples, see the NavigationMenu Theme section. Summary:
- Use the theme system to override childLink classes for active and hover states. - Apply your desired Tailwind background classes (e.g., bg-blue-500, hover:bg-blue-100) in the theme override. If you need a code example for app.config.ts, let me know!

@kapa.ai right?

export default defineAppConfig({
  ui: {
    colors: {
      primary: 'blue',
    },
    active: {
      true: {
        childLink: 'bg-blue-500 text-white',
        childLinkIcon: 'text-white'
      },
      false: {
        childLink: [
          'hover:bg-blue-100 text-default hover:text-blue-700',
          'transition-colors'
        ],
        childLinkIcon: [
          'text-dimmed group-hover:text-blue-500',
          'transition-colors'
        ]
      }
    }
  },
})

export default defineAppConfig({
  ui: {
    colors: {
      primary: 'blue',
    },
    active: {
      true: {
        childLink: 'bg-blue-500 text-white',
        childLinkIcon: 'text-white'
      },
      false: {
        childLink: [
          'hover:bg-blue-100 text-default hover:text-blue-700',
          'transition-colors'
        ],
        childLinkIcon: [
          'text-dimmed group-hover:text-blue-500',

Let me check the knowledge base for you again. One moment! :books: ---------------------- Your configuration is not quite correct for customizing the active and hover background color of NavigationMenu items in Nuxt UI. According to the knowledge sources, the active and childLink theme overrides for NavigationMenu should be placed under the navigationMenu key inside the ui object in your app.config.ts, not at the root of ui or as a global active property. Here’s the correct structure based on the documentation:

export default defineAppConfig({
  ui: {
    navigationMenu: {
      variants: {
        active: {
          true: {
            childLink: 'bg-blue-500 text-white',
            childLinkIcon: 'text-white'
          },
          false: {
            childLink: [
              'hover:bg-blue-100 text-default hover:text-blue-700',
              'transition-colors'
            ],
            childLinkIcon: [
              'text-dimmed group-hover:text-blue-500',
              'transition-colors'
            ]
          }
        }
      }
    }
  }
})

export default defineAppConfig({
  ui: {
    navigationMenu: {
      variants: {
        active: {
          true: {
            childLink: 'bg-blue-500 text-white',
            childLinkIcon: 'text-white'
          },
          false: {
            childLink: [
              'hover:bg-blue-100 text-default hover:text-blue-700',
              'transition-colors'
            ],
            childLinkIcon: [
              'text-dimmed group-hover:text-blue-500',
              'transition-colors'
            ]
          }
        }
      }
    }
  }
})

- Place your overrides under ui.navigationMenu.variants.active. - The colors property is not used for this kind of override. - This structure matches the theming system described in the NavigationMenu Theme documentation. Summary:
Move your active overrides under ui.navigationMenu.variants for them to take effect. If you follow this structure, your custom background colors for active and hover states will work as expected. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai not working ? export default defineAppConfig({ ui: { colors: { primary: 'blue', }, navigationMenu: { variants: { active: { true: { childLink: 'bg-blue-500 text-white', childLinkIcon: 'text-white' }, false: { childLink: [ 'hover:bg-blue-100 text-default hover:text-blue-700', 'transition-colors' ], childLinkIcon: [ 'text-dimmed group-hover:text-blue-500', 'transition-colors' ] } } } } }, })

Let me check the knowledge base for you again. One moment! :books: ---------------------- Your configuration is almost correct in terms of structure, but based on the knowledge sources, the active variant for navigationMenu should be placed under the variants key, which is correct in your example. However, the knowledge sources do not explicitly confirm that customizing the active variant in this way will work for the childLink slot specifically, as the documentation only shows the default theme structure and not a full example of overriding it in app.config.ts with custom classes. Additionally, the colors property is not related to the active state styling for navigationMenu items, so you can omit it if your goal is only to change the background color on active/hover. Here is the relevant structure from the knowledge source:

export default defineAppConfig({
  ui: {
    navigationMenu: {
      variants: {
        active: {
          true: {
            childLink: 'bg-elevated text-highlighted',
            childLinkIcon: 'text-default'
          },
          false: {
            childLink: [
              'hover:bg-elevated/50 text-default hover:text-highlighted',
              'transition-colors'
            ],
            childLinkIcon: [
              'text-dimmed group-hover:text-default',
              'transition-colors'
            ]
          }
        }
      }
    }
  }
})

export default defineAppConfig({
  ui: {
    navigationMenu: {
      variants: {
        active: {
          true: {
            childLink: 'bg-elevated text-highlighted',
            childLinkIcon: 'text-default'
          },
          false: {
            childLink: [
              'hover:bg-elevated/50 text-default hover:text-highlighted',
              'transition-colors'
            ],
            childLinkIcon: [
              'text-dimmed group-hover:text-default',
              'transition-colors'
            ]
          }
        }
      }
    }
  }
})

You are following this structure, so your approach is consistent with the documentation. If it is not working, possible reasons could be: - Cache: Try restarting your dev server after making changes to app.config.ts. - Class specificity: Make sure there are no other classes overriding your custom classes. - Component usage: Ensure you are using the correct component (UNavigationMenu) and that your items are using the childLink slot. In summary:
Your configuration matches the documented structure for theming the NavigationMenu. If it is not working, the knowledge sources do not provide further troubleshooting steps. Double-check your setup and try restarting your dev server. If issues persist, consult the official documentation or community for more advanced troubleshooting.

@kapa.ai I restarted the server but still did not work, there was another way

kapa.ai•7mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I'm sorry, but the knowledge sources do not provide an explicit, working example of overriding the active or hover background color for NavigationMenu items via app.config.ts or another method. While the theme structure and default classes are shown, there is no clear documentation confirming that custom classes for childLink in the active variant will be applied as expected, nor is there an alternative method described for this specific customization. If the documented approach is not working after restarting your server, the knowledge sources do not offer another officially supported way to achieve this. You may need to consult the official Nuxt UI documentation or community for further assistance, as the current sources do not contain enough information to resolve this issue with certainty.
