“UDM is a lightweight and accessible javascript menu, which provides useable content to all browsers—- including screenreaders, search-engines and text-only browsers. But accessibility shouldn’t mean compromise, and so UDM has a sophisticated range of design and usability controls, many of which are unique to this script. The navigation bar is simply a list of links. You can use Tab for navigation, and Enter to activate links, or whatever keystrokes you would normally use. To the best of our knowledge, Ultimate Drop Down Menu is the ONLY fully-featured and accessible DHTML menu in the world!”
