Using Lists for DHTML Menus

TransMenus
TransMenus is a modular script that creates actions for two CSS classes: “popUpMenu” and “collapsibleMenu”. When the “popUpMenu” class is assigned to a nested ul element, that element is displayed as a pop-up menu activated by the mouseover event of its parent li element. Similarly, When the “collapsibleMenu” is assigned to a nested ul element, that element is displayed as a collapsible menu expanded (i.e. made visible) on the click event of its parent li element.
