Nuxt nested layout

Hi everyone, We're having a problem with Nuxt and nested layouts. If there are more than one nested layout, the layout stacks. For example two headers and two sidebars, that we don't want to see please refer to the linked stackblitz. https://stackblitz.com/~/github.com/kilisei/nuxt-layout?file=package.json Please reply if you know how to fix this. Thank you for your help :)

Hi @Kilisei. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the information provided in the knowledge sources, I can offer some insights on how to handle nested layouts in Nuxt without causing unwanted stacking of elements. Here's how you can approach this issue: 1. Use a single layout with conditional rendering: Instead of using multiple nested layouts, you can create a single layout that conditionally renders different components based on the current route. This approach avoids the stacking problem you're experiencing. Docs > Guide > Directory-structure > layouts suggests using named layouts and dynamically changing them: 
   <script setup lang="ts">
   // You might choose this based on an API call or logged-in status
   const layout = "custom";
   </script>

   <template>
     <NuxtLayout :name="layout">
       <NuxtPage />
     </NuxtLayout>
   </template>
   
   <script setup lang="ts">
   // You might choose this based on an API call or logged-in status
   const layout = "custom";
   </script>

   <template>
     <NuxtLayout :name="layout">
       <NuxtPage />
     </NuxtLayout>
   </template>
2. Use nested routes instead of nested layouts: Stack Overflow Post > Using two layouts simultaneously in Nuxt 3 provides a solution using nested routes: 
   The solution is to use nested routes. In the `pages` folder I created a `profile.vue` and put there shared parts and a <NuxtPage/>. After that, I created a `profile` folder and put there an `index.vue` and a `favorite.vue` with the content. This way it should work with both `default` layout and a `profile` (which is basically the shared parts in the parent component, located in `pages` and not `layouts` like in the case with `default`). So we're using `profile` here as a page, but it acts like a layout, where we put a <NuxtPage/> instead of a <slot>.

So we're using `profile` here as a page, but it acts like a layout, where we put a <NuxtPage/> instead of a <slot>.
3. Ensure proper layout structure: Make sure your layouts are structured correctly. The Docs > Guide > Directory-structure > layouts states: "Unlike other components, your layouts must have a single root element to allow Nuxt to apply transitions between layout changes - and this root element cannot be a <slot />." 4. Use ClientOnly component: If the issue persists, you might try wrapping your layout in a ClientOnly component as suggested in a Github Issue comment: 
   <ClientOnly>
   <NuxtLayout>
   <NuxtPage />
   </NuxtLayout>
   </ClientOnly>
   
   <ClientOnly>
   <NuxtLayout>
   <NuxtPage />
   </NuxtLayout>
   </ClientOnly>
However, note that this forces everything to be client-side rendered, which might not be ideal for SEO or performance. 5. Check for hydration issues: Make sure there are no hydration mismatches between server-side and client-side rendering. Ensure that your layouts and pages are consistent across both environments. If these approaches don't resolve your specific issue, you might need to provide more details about your exact setup or consider creating a minimal reproduction of the problem for further investigation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@l422y Thank you for your reply, but this does not solve my problem, I want this page to have only the extra info of the assigned layout, not the company/customer extra info in one page. or am i understanding you wrong we want to use a slot ok, thank you, then what I am trying to do is not possible the way I have been doing it, thank you for your help. :) @l422y

Hello I have exactly the same question I think ^^ Let's say I have 3 elements on my page : - menu - submenu - page I want my menu to be there no matter what, but my submenu only on certain pages What I would like to do is something like : - menu.vue (layout) - submenu.vue (layout) that includes the menu - page.vue (page) that includes the submenu (and thus the menu) In your solution, what I would need to do is either : - Add a condition to load the submenu depending on the page/route - Add the menu in my layouts The first solution feels clonky with extra verification. The second is "fine", I would have the menu as a code repetition, but by making it a component at least the modifications will be centralized Is there a way to nest layouts, or should I treat the "menu" layout as a component and include it in all my layouts ? Thanks 🙂

Hey, we ended up using definePageMeta, specifing a custom sidemenu Entry and using it in the Sidemenu-Component via the route.meta to retrive it. In the Sidemenu-Component: 
const sidemenuOptions = ref<SidemenuOptions>();

const router = useRouter();
const route = useRoute();
const { t } = useI18n();

onServerPrefetch(updateSidemenu);
onBeforeMount(updateSidemenu);
watch(route, updateSidemenu);

/**
 * Scans the current route and walks up the parents for a sidemenu definition in
 * the Page Metadata and return it if found.
 * @returns The sidebar definition or undefined if not found.
 */
function scanForSidemenu() {
  let pathSegment = route.fullPath;
  while (pathSegment.length > 0) {
    const match = router.resolve(pathSegment);
    if (match?.meta?.sidemenu) {
      return match.meta.sidemenu;
    }

    const lastSlash = pathSegment.lastIndexOf('/');
    if (lastSlash === -1) {
      break;
    }

    pathSegment = pathSegment.substring(0, lastSlash).trim();
  }
}

function updateSidemenu() {
  const metaSidemenu = scanForSidemenu();
  if (metaSidemenu) {
    const sidemenu = typeof metaSidemenu === 'function' ? metaSidemenu({ t, route }) : metaSidemenu;
    sidemenuOptions.value = sidemenu;
  }
}
const sidemenuOptions = ref<SidemenuOptions>();

const router = useRouter();
const route = useRoute();
const { t } = useI18n();

onServerPrefetch(updateSidemenu);
onBeforeMount(updateSidemenu);
watch(route, updateSidemenu);

/**
 * Scans the current route and walks up the parents for a sidemenu definition in
 * the Page Metadata and return it if found.
 * @returns The sidebar definition or undefined if not found.
 */
function scanForSidemenu() {
  let pathSegment = route.fullPath;
  while (pathSegment.length > 0) {
    const match = router.resolve(pathSegment);
    if (match?.meta?.sidemenu) {
      return match.meta.sidemenu;
    }

    const lastSlash = pathSegment.lastIndexOf('/');
    if (lastSlash === -1) {
      break;
    }

    pathSegment = pathSegment.substring(0, lastSlash).trim();
  }
}

function updateSidemenu() {
  const metaSidemenu = scanForSidemenu();
  if (metaSidemenu) {
    const sidemenu = typeof metaSidemenu === 'function' ? metaSidemenu({ t, route }) : metaSidemenu;
    sidemenuOptions.value = sidemenu;
  }
}
In the Page wanting a Sidemenu: 
definePageMeta({
  sidemenu: ({ t }) => ({
    // Whatever structure you want for your Sidemenu data
    // ...
  }),
});
definePageMeta({
  sidemenu: ({ t }) => ({
    // Whatever structure you want for your Sidemenu data
    // ...
  }),
});
For typescript to recognise the new PageMeta you need to add this to your env.d.ts: 
declare module '#app' {
  interface PageMeta {
    /**
     *
     * NOTE: Due to how definePageMeta works the sidemenu is not allowed to reference variables from the script-setup block. Imports should work fine.
     */
    sidemenu?: (options: { t: ReturnType<typeof useI18n>['t']; route: ReturnType<typeof useRoute> }) => SidemenuOptions;
  }
}
declare module '#app' {
  interface PageMeta {
    /**
     *
     * NOTE: Due to how definePageMeta works the sidemenu is not allowed to reference variables from the script-setup block. Imports should work fine.
     */
    sidemenu?: (options: { t: ReturnType<typeof useI18n>['t']; route: ReturnType<typeof useRoute> }) => SidemenuOptions;
  }
}
Hope this helps! Feel free to ask if something is unclear! 🙂
