Hover over menu items.
'Sliding + Fading' effect is used when the submenus appear (var transition=103;).
The menu items structure is generated using HTML unordered list (UL and LI tags) inside your HTML page.
It is very simple to edit the menu. Add/change <UL> or <LI> tags to add/change menu items, submenus and separators.
All menu items will be visible for search engines due to this structure.
