Screen Reader

Toggleable panels use a content toggle button at the header that has aria-controls to define the id of the content section along with aria-expanded for the visibility state. The value to read the button defaults to the value of the header property and can be customized by defining an aria-label or aria-labelledby via the toggleButtonProps property.

The content uses region, defines an id that matches the aria-controls of the content toggle button and aria-labelledby referring to the id of the header.
