add horizontal menu to website

I need a menu adding to a single webpage. The menu should be similar to the one here -? <[login to view URL]> The menu should have? 6 top level categories each with 5 dropdown choices ( these can be named link1, link2 etc ). They can be linked to any sample page as I will change these. The menu should be all white as shown on the link above, but this should be changeable if I decide on a new color scheme. I have attached the page the menu should be placed on. No flash please and the menu must work on both IE and Firefox
