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 DropDownList keyboard navigation is enabled by default, as demonstrated in this demo.

The DropDownList supports the following keyboard shortcuts:

Focus

Keyboard legend

  • up arrow highlights previous item
  • down arrow highlights next item
  • left arrow highlights previous item
  • right arrow highlights next item
  • home selects first item in the list
  • end selects last item in the list
  • page up scrolls the popup up
  • page down scrolls the popup down
  • enter selects highlighted item
  • esc closes the popup
  • alt down arrow opens the popup
  • space opens the popup / selects highlighted item
  • alt up arrow closes the popup
