Multi - Level Drop Down Menus in a tpl file

[Tristan2036]

Okay i have been looking my best for this problem on forum.
I have a website script written in php, now the menu it has is in php and uses a tpl file.
This is very crude compared to what i need, now i post here in DHTML because the DHTML drop down menus are more what i need.
here's the problem.
I want to install this for the top navigation bar. It should appear on the whole site.
But how do you get a DHTML menu into php script.
The current menu is php script, and it is linked in each of the php pages at the bottom.
And it needs to have the ability to recognize whether the user is logged in.
Thanks
