Webpage Drop Down Menus

[pufame]

I have recently begun revamping our team's webpage and I find that it is a pain getting a good navigation system (Meaningly a drop-down menu bar). I have spent countless hours trying to get this one menu (JavaScript based) to work and it works OK now, but looking at outher team's pages I know it could be better. What I'm looking for in the menu is...

1) Based on top - not on side

2) Ease to update - we need to be able to edit it through the code, not in an external app.

3) Ease to move - One of the biggest problems I've been having with the one we use now is it was designed to be stationed at the top-left corner of the page. I did get it to move but it ends up in different places with different browsers

4) Entire button clicks, not just text - sounds like a dumb request but it makes a difference

5) It should be truely "pop-out" meaning the sub-menus shoulod appear on a mouse over, not on a click.

...If any team has a menu like this or know of a place to get a menu like this please reply to this message. I will most likely keep working on our current menu, but like I said before I'm not really a fan of it. Or I may just do my own HTML based menu if all else fails.

Thanks - Pufame
