Description

Keyboard navigation provides all web and app users with a fast keyboard-only navigation capability and is also part of the web accessibility features–it enables users with disabilities to fully control their website or app access through the keyboard.

By default, users can only navigate to links, buttons, and form controls with a keyboard. The navigation order in which interactive items receive keyboard focus has to be logical and intuitive. Generally, keyboard navigation logic needs to follow the visual horizontal and vertical flow of the page, for example, left to right and top to bottom, header first followed by the main and then the page navigation.

The keyboard navigation of the Telerik UI for ASP.NET Core ContextMenu is always available as demonstrated in this demo.

The ContextMenu supports the following keyboard shortcuts:

Supported Keys and User Actions

  • Home Focuses the first item.
  • End Focuses the last item.
  • Down Arrow Focuses the next item.
  • Up Arrow Focuses the previous item.
  • Right Arrow If the item has children, opens the item and focuses the first child. For child items without children, focuses and opens the next root item.
  • Left Arrow (For root items) opens the item group and focuses the last child. (For child items) closes the item group and focuses the parent item.
  • Enter or Space Selects the focused item. If the item has children, opens the item group and focuses the first child. If the item does not have children and has a URL, navigates to the specified URL.
  • Shift + Tab Tabs away from the ContextMenu on the next focusable page element.
  • Shift + F10 When the target element is focused, the command opens the ContextMenu.
  • Esc Closes the innermost open group. If no item group is opened, closes the ContextMenu.
