Add Dropdowns to Menus
Adding dropdowns to menus requires the use of JavaScript. The Y.Menu module adds dropdown functionality and the ability to create JavaScript menus. It uses csslist to style these menus, so they look identical.
Fixed Menus
Fixed menus can be created by adding the yui3-menu-fixed class name to the wrapper. This will fix a menu to the top of the page.
