#Layouts

Layout components are used to wrap pages. Layouts should contain components like headers, footers or sidebars that will be used across the site.

Layouts are just  .vue components located in src/layouts and need to be declared as a global component or imported per page to be used.

Every layout requires a <slot> component. This is where the content coming from pages and templates will be inserted. Layouts can have multiple slots.

<!-- Layout -->
<template>
  <div>
    <header />
    <slot></slot> <!-- Page content will be inserted here -->
    <footer />
  </div>
</template>

#Import layouts

When you have created a layout you need to import it to your pages and templates. This is done inside the <script> tag.

<!-- Page -->
<template>
  <Layout>
    Add page content here
  </Layout>
</template>

<script>
import Layout from '~/layouts/Default.vue'

export default {
  components: {
    Layout
  }
}
</script>

#Make a layout global

If you don't want to import the layout into every page or template you can make a layout global. To make a layout global go to src/main.js and import your layout file into this file.

For example:

// src/main.js

import Layout from '~/layouts/Default.vue'

Then make the layout global inside the export function.

// src/main.js

import Layout from '~/layouts/Default.vue'

export default function (Vue, { head, router, isServer }) {
  Vue.component('Layout', Layout)
}

You can now use <Layout> anywhere in your Gridsome project without importing it to every page:

<!-- Page -->
<template>
  <Layout>
    Add page content here
  </Layout>
</template>

#Passing Props to layouts

Since layouts work like components, it is possible to pass Props to layouts. For example a page can look like this:

<!-- Page -->
<template>
  <Layout :sidebar="true">
    Add page content here
  </Layout>
</template>

This will pass a Prop to a layout with sidebar = true. In the Layout component this could look like this:

<!-- Layout -->
<template>
  <div>
    <div class="main-content">
      <slot></slot>
    </div>
    <div v-if="sidebar">
      Lets show the sidebar!
    </div>
  </div>
</template>

<script>
export default {
  props: ['sidebar']
}
</script>

#Multiple content slots

To add multiple slots to a layout you need to name them. In this example we have added a sidebar slot that will only show if the page has sidebar content.

<!-- Layout -->
<template>
  <div>
    <slot /> <!-- Default slot -->
    <div class="sidebar" v-if="$slots.sidebar">
      <slot name="sidebar"></slot> <!-- Sidebar slot -->
    </div>
  </div>
</template>

Pages can now add content to this slot like this:

<!-- Page -->
<template>
  <Layout>
    This is the default content

    <template slot="sidebar">
      This will be added to sidebar slot from the page
    </template>
  </Layout>
</template>

#Master layout

You can create a master layout by adding an App.vue file to src root. This will let you keep your header, footer on all pages and add page transitions.

A simple App.vue file looks like this:

<template>
  <div id="app">
    <router-view />
  </div>
</template>
