AllWebMenus Style Example - Multiple Columns
While the menu appearance looks normal at first sight, the submenus clickable areas are smaller than the submenus total space. Actually, each subgroup is a 5x5 set of items defined as a Vertical, 3-Column submenu.
Note that semi-transparency effect is achieved with 32bit png images which is supported by major modern browsers (IE7, Firefox 2, Opera 9 etc).
