Accessibility Standards Compliance

The ContextMenu component complies to all Section 508 and WCAG 2.x standards criteria.

Keyboard Navigation

A user can use the following keys to interact with the ContextMenu component:

Key Action
← Closes the submenu and focuses on its parent item.
→ Opens the submenu of the focused item.
Home Sets focus to the first item in the menu/submenu.
End Sets focus to the last item in the menu/submenu.
Space Switches the focused item to the selected state.
Enter Chooses the focused item.

Use the registerKeyHandler(key, handler) method to implement a custom handler for a key.

  •  
  •     ngAfterViewInit () {
  •         this.contextMenu.instance.registerKeyHandler('backspace', function(e) {
  •             // The argument "e" contains information on the event
