# Layouts Directory
|
|
|
|
Nuxt provides a customizable layouts framework you can use throughout your application, ideal for extracting common UI or code patterns into reusable layout components.
|
|
|
|
Layouts are placed in the `layouts/` directory and will be automatically loaded via asynchronous import when used. Layouts are used by adding `<NuxtLayout>` to your `app.vue`, and either setting a `layout` property as part of your page metadata (if you are using the `~/pages` integration), or by manually specifying it as a prop to `<NuxtLayout>`. (**Note**: The layout name is normalized to kebab-case, so `someLayout` becomes `some-layout`.)
|
|
|
|
If you only have a single layout in your application, we recommend using [app.vue](/docs/guide/directory-structure/app) instead.
|
|
|
|
::alert{type=warning}
|
|
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 />`.
|
|

|
|
|
|
## Enabling the Default Layout
|
|
|
|
Add a `~/layouts/default.vue`:
|
|
|
|
```vue [layouts/default.vue]
|
|
<template>
|
|
<div>
|
|
Some default layout shared across all pages
|
|
<slot />
|
|
</div>
|
|
</template>
|
|
```
|
|
|
|
In a layout file, the content of the layout will be loaded in the `<slot />`, rather than using a special component.
|
|
|
|
If you use a `app.vue` you will also need to add `<NuxtLayout>`:
|
|
|
|
```vue [app.vue]
|
|
<template>
|
|
<NuxtLayout>
|
|
some page content
|
|
</NuxtLayout>
|
|
</template>
|
|
```
|
|
|
|
## Setting Another Layout
|
|
|
|
```bash
|
|
-| layouts/
|
|
---| default.vue
|
|
---| custom.vue
|
|
```
|
|
|
|
You can directly override the default layout like this:
|
|
|
|
```vue{}[app.vue]
|
|
<template>
|
|
<NuxtLayout :name="layout">
|
|
<NuxtPage />
|
|
</NuxtLayout>
|
|
</template>
|
|
|
|
<script setup>
|
|
// You might choose this based on an API call or logged-in status
|
|
const layout = "custom";
|
|
</script>
|
|
```
|
|
|
|
Alternatively, you can override the default layout per-page like this:
|
|
|
|
::code-group
|
|
|
|
```vue{}[pages/index.vue]
|
|
<script>
|
|
// This will work in both `<script setup>` and `<script>`
|
|
definePageMeta({
|
|
layout: "custom",
|
|
});
|
|
</script>
|
|
```
|
|
|
|
```vue{}[app.vue]
|
|
<template>
|
|
<NuxtLayout>
|
|
<NuxtPage />
|
|
</NuxtLayout>
|
|
</template>
|
|
```
|
|
|
|
```vue [layouts/custom.vue]
|
|
<template>
|
|
<div>
|
|
Some *custom* layout
|
|
<slot />
|
|
</div>
|
|
</template>
|
|
```
|
|
|
|
```vue [layouts/default.vue]
|
|
<template>
|
|
<div>
|
|
A *default* layout
|
|
<slot />
|
|
</div>
|
|
</template>
|
|
```
|
|
|
|

|
|
|
|
::alert{type=info}
|
|

|
## Changing the Layout Dynamically
|
|
|
|
You can also use a ref or computed property for your layout.
|
|
|
|
```vue
|
|
<template>
|
|
<div>
|
|
<button @click="enableCustomLayout">Update layout</button>
|
|
</div>
|
|
</template>
|
|
|
|
<script setup>
|
|
function enableCustomLayout () {
|
|
setPageLayout('custom')
|
|
}
|
|
definePageMeta({
|
|
layout: false,
|
|
});
|
|
</script>
|
|
```
|
|
|
|
::LinkExample{link="/docs/examples/routing/layouts"}
|

|
|
|
## Overriding a Layout on a Per-page Basis
|
|
|
|
If you are using the `~/pages` integration, you can take full control by setting `layout: false` and then using the `<NuxtLayout>` component within the page.
|
|
|
|
::code-group
|
|
|
|
```vue [pages/index.vue]
|
|
<template>
|
|
<div>
|
|
<NuxtLayout name="custom">
|
|
<template #header> Some header template content. </template>
|
|
|
|
The rest of the page
|
|
</NuxtLayout>
|
|
</div>
|
|
</template>
|
|
|
|
<script setup>
|
|
definePageMeta({
|
|
layout: false,
|
|
});
|
|
</script>
|
|
```
|
|
|
|
```vue [layouts/custom.vue]
|
|
<template>
|
|
<div>
|
|
<header>
|
|
<slot name="header">
|
|
Default header content
|
|
</slot>
|
|
</header>
|
|
<main>
|
|
<slot />
|
|
</main>
|
|
</div>
|
|
</template>
|
|
```
|
|
|
|
::
|
|
|
|
::alert{type=warning}
|
|
If you use `<NuxtLayout>` within your pages, make sure it is not the root element (or disable layout/page transitions).
