# Collapsible Field

Source: https://payloadcms.com/docs/fields/collapsible

The Collapsible Field is presentational-only and only affects the Admin Panel. By using it, you can place fields within a nice layout component that can be collapsed / expanded.

To add a Collapsible Field, set the `type` to `collapsible` in your [Field Config](/docs/v3/fields/overview.md):

```ts
import type { Field } from 'payload'

export const MyCollapsibleField: Field = {
  // ...
  // highlight-start
  type: 'collapsible',
  fields: [
    // ...
  ],
  // highlight-end
}
```

| **`fields`** \* | Array of field types to nest within this Collapsible.                                                                                                                        |

_\* An asterisk denotes that a property is required._

## Admin Options

To customize the appearance and behavior of the Collapsible Field in the [Admin Panel](/docs/v3/admin/overview.md), you can use the `admin` option:

```ts
import type { Field } from 'payload'

export const MyCollapsibleField: Field = {
  // ...
  admin: {
    // highlight-line
    // ...
  },
}
```

The Collapsible Field inherits all of the default admin options from the base [Field Admin Config](/docs/v3/fields/overview.md#admin-options), plus the following additional options:

| Option              | Description                     |
| ------------------- | ------------------------------- |
| **`initCollapsed`** | Set the initial collapsed state |

## Example

```ts
import type { CollectionConfig } from 'payload'

export const ExampleCollection: CollectionConfig = {
  slug: 'example-collection',
  fields: [
    {
      label: ({ data }) => data?.title || 'Untitled',
      type: 'collapsible', // required
      fields: [
        // required
        {
          name: 'title',
          type: 'text',
          required: true,
        },
        {
          name: 'someTextField',
          type: 'text',
          required: true,
        },
      ],
    },
  ],
}
```
