To add a Collapsible Field, set the `type` to `collapsible` in your [Field Config](./overview):
```ts
import type { Field } from 'payload'
export const MyCollapsibleField: Field = {
// ...
// highlight-start
type: 'collapsible',
fields: [
// ...
],
// highlight-end
}
```
## Config Options
| Option | Description |
| --------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **`label`** \* | A label to render within the header of the collapsible component. This can be a string, function or react component. Function/components receive `({ data, path })` as args. |

admin: { // highlight-line
// ...
