Description

Adds useful context to the useCollapsible hook and exports it for easier import.

Example usage:

import React from 'react'

import { useCollapsible } from 'payload/components/utilities'

const CustomComponent: React.FC = () => {
  const { collapsed, toggle } = useCollapsible()
  return (
    <div>
      <p className="field-type">I am {collapsed ? 'closed' : 'open'}</p>
      <button onClick={toggle} type="button">
        Toggle
      </button>
    </div>
  )
}
