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.


Admin Config

Example
collections/ExampleCollection.ts
import { CollectionConfig } from 'payload/types'
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,
},
],
},
],
}
