I made a tests nav bar for my forum on http://ricocheting.com/js/drop.html

and it came out great but the script wont work on the actual nav bar , but will work in the widgets etc why is this? Because I wanted to replace my current nav bar with these kind.

Replacing the navbar on a forumotion board requires extensive knowledge of javascript and HTML. That's why you don't see customized drop-down navbars on any forumotion boards. Well...not entirely true. I do know of one board that has a drop-down navbar.

Without a LOT of customized javascript and HTML coding, I don't even need to see the HTML you've generated to know that one very important link doesn't work on your replacement navbar. You can't log out without a session ID and access key, and the unique ID and access key are generated by the board software and placed in the navbar logout button. Your replacement code needs both the ID and key in the logout link in order for a person to log out.
