# Custom Layouts <small></small>
> Custom Layouts allow for building new ways to view or interact with Items via the Collection Detail pages.
> [Learn more about Layouts](/getting-started/glossary/#layouts).
## 1. Setup the Boilerplate
Every layout is a standalone "package" that contains at least a metadata file and a Vue component. We recommend using
the following file structure:
```
src/
index.js
layout.vue
```
### src/index.js
```js
import { ref } from 'vue';
import LayoutComponent from './layout.vue';
export default {
id: 'custom',
name: 'Custom',
icon: 'box',
component: LayoutComponent,
slots: {
options: () => null,
sidebar: () => null,
actions: () => null,
},
setup() {
const name = ref('Custom Layout');
return { name };
},
};
```
- `id` — The unique key for this layout. It is good practice to scope proprietary layouts with an author prefix.
- `name` — The human-readable name for this layout.
- `icon` — An icon name from the [material icon set](/getting-started/glossary/#material-icons), or the extended list of
Directus custom icons.
- `component` — A reference to your Vue component.
::: tip TypeScript
See
[the TypeScript definition](https://github.com/directus/directus/blob/20355fee5eba514dd75565f60269311187010c66/app/src/layouts/types.ts#L4-L9)
for more info on what can go into this object.

### src/layout.vue
```vue
<template>
<div>
<p>Name: {{ name }}</p>
<p>Collection: {{ collection }}</p>
</div>
</template>
<script>
export default {
inheritAttrs: false,
props: {
collection: {
type: String,
required: true,
},
name: {
type: String,
required: true,
},
},
};
</script>
```
The props you can use in a layout are:
- `collection` — The current collection's name.
- `selection` (sync) - Any currently selected items.
- `layout-options` (sync) - The user's current saved layout options.
- `layout-query` (sync) - The user's layout query parameters. (eg: sort, limit, etc)
- `filters` (sync) - The user's currently active filters.
- `search-query` (sync) - The user's current search query.
## 2. Install Dependencies
Set up a package.json file by running:
```bash
npm init -y
```
To be read by the Admin App, your custom layouts's Vue component must first be bundled into a single `index.js` file. We
recommend bundling your code using the directus-extension CLI from our `@directus/extensions-sdk` package. The CLI
internally uses a Rollup configuration tailored specifically to bundling Directus extensions. To install the Extension
SDK, run this command:
```bash
npm i -D @directus/extensions-sdk
```
For the directus-extension CLI to recognize the extension type, the input path and the output path, add this field to
the root of the `package.json` file:
```json
"directus:extension": {
"type": "layout",
"path": "dist/index.js",
"source": "src/index.js",
"host": "^9.0.0-rc.87",
"hidden": false
}
```
## 3. Develop Your Custom Layout
The layout itself is simply a Vue component, which provides a blank canvas for creating anything you need.
## 4. Build and Deploy
To build the layout for use within Directus, run:
```bash
npx directus-extension build
```
Finally, move the output from your layout's `dist` folder into your project's `/extensions/layouts/my-custom-layout`
folder. Keep in mind that the extensions directory is configurable within your env file, and may be located elsewhere.
