Guidance

Accessibility

Keyboard support

  • Enter or Space to select the highlighted item.
  • Tab to move the focus sequentially through the list of focusable items.
  • Shift + Tab to move the focus sequentially through the list of focusable items in reversed order.

Focus Management

  • When the modal is opened, the entire modal is the default focus state. Most screen readers will announce the entire dialog content.
  • Focus is trapped within the modal and users can then navigate through the dialog actions with the keyboard.
  • Escape will close the modal. To disable exiting when users press the Escape key, set the escapeExits prop to false
  • When the modal closes, focus returns to the element that was focused just before the modal is activated
  • To place the focus inside of the dialog on activating the modal, set the dialog focus using the initialFocus prop with boolean prop focusDialog set to false
