ARIA Listboxes (Popup Listbox - Internal content)

The popup listbox is optimized for screen reader and keyboard only users:

  • The content will be inserted inline with the triggering element, and focus will automatically move to the first listbox option.
  • Press the Arrow keys to change options, or press Home or End to jump to the beginning or end of the list.
  • Press PageUp or PageDown to jump backward or forward incrementally.
  • Press any letter or number to jump to an item starting with that character or digit.
  • Press Enter on a listbox option to close the popup and save the selection.
  • To cancel, press Tab to set focus to the Close link and press Enter to close the popup, or press Escape to close the popup directly.
  • When closed, focus will move back to the triggering element.
