• Places the displayed content next in DOM order after the button.
• Uses some ARIA magic to augment the semantics and behaviour.
• Displays or dismisses content on click, press or tap (also dismisses on esc key press).
• Conveys state (collapsed or expanded) to AT users.
• When initially displayed content is announced by (most) screen readers that support aria-live.
• Screen readers users can also virtual cursor through and interact with the displayed content.
• keyboard only users can interact with controls in the displayed content.
