There are a ton of JavaScript options available. A quick Google for the phrase "Javascript Tree Menu" found this nifty little gem:

TreeMenu.net

I didn't look to hard at it, but most of these collapsable menu driven JavaScripts can be adopted with PHP to be database driven pretty easily.

Well, for the display in the browser here's a couple of good a examples.

With regards to how you're going to organize menu elements in the database it will very much depend on the nature of your data but a good general model is for each element to have an attribute, let's call it parent, which contains the unique id of the element which comes above it in the tree. Element(s) at the root of the tree then have a parent id of zero. This makes structure makes it very quick and easy to pull out large, complex, nested loops.

Be wary of DHTML, remember that many of the examples out there are not standards compliant and can therefore not be garunteed to be forwards compatible. I am not sure if the Tree Menu Javascript Applet is using deracated methods or not but always be careful and check.

NB: Frames are deprecated, frameless option may be good though. Even if it's not it has some really nice features there which could be used for a standards compliant version.

Personally I quite like Destroydrop's implementation.
But as as already been noted, this is a client-side task, and therefore an inappropriate question in a PHP forum.
