 ## 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.
