To use this menu, you'll need a source of data that provides menu options in the format:
ID, Parent ID, name, link and level.
The menu will only take 3 nested levels
I used a "start with/connect by" query to get my data
I would recommend modifying your page template to to place this in the tab area on page 0.
Credit goes to Stu Nicholls for providing the menu code.
