The Details component is an HTML <details> element without native browser styling that optionally uses the render props pattern to pass its state to child components.

You are responsible for rendering your own <summary>. To style your summary element like a Button, you can use the is prop:

<Button is="summary">Summary text</Button>

With static children

Click me

This should show and hide

  <Button is="summary">Click me</Button>
  <p>This should show and hide</p>

With children as a function

The render function gets an object with two keys:

  • open is a boolean reflecting the <details> element's open attribute, and can be used to conditionally show or hide content.
  • toggle is a function that can be assigned to event handlers to trigger toggling of the open state.

If you use this form or the render prop (see below), you must attach the toggle prop as an event listener. If you don't the render function will not be called when the element is toggled by the native browser behavior.


This should show and hide

  {({open, toggle}) => (
      <Button is="summary" onClick={toggle}>
        {open ? 'Hide' : 'Show'}
      <p>This should show and hide</p>

With render prop

The Details component also accepts a render function prop.

Open? false

This is the content.

<Details render={({open, toggle}) => (
    <Button is="summary" onClick={toggle}>Open? {String(open)}</Button>
    <p>This is the content.</p>
)} />
