Well, that page isn’t really a menu, just an alphabetical listing. It would be difficult (read: impossible) to incorporate that many items into a menu.
However, if you wanted more than just a list of pages, such as a list of links to pages but also information about those links, you could incorporate that information into a table and then use the Tablesorter plugin for jQuery: http://tablesorter.com/docs/
I’ve used it before; it’s pretty handy (and cool) when used in the right place.
