What is possible to do (only several possibilities):
- usual textual menu with CSS highlight;
- graphical menu with javascript highlight;
- dropdown javascript menu with using of divs;
- multi-level menu, which could be automatically opened when you navigate from page to page;
- menu with automatic generated GIF/JPG/PNG images, contains strings from point titles;
- menu, which could be open/close on current page without content reload;
- flash menu with full control from back-office;
- breadcrumbs menu or current level submenu;
- and much more.
In another words, you able to create menu with any kind of complexity. All the menus will be used on page with macros like this: $Menu[menuid: footermenu; design: menupath]$. And all kind of menu will be controlled similarly.
