Creating Dynamic lists php

[Deleted User 234324]

Hiya folks

Looking for a method to create a dynamic list in php.

Essentially i will have 2-3 lists, a primary list which will contain the "headers" followed by sub category lists.

What im looking for is a method where i can have a list of headers and when someone clicks on one of the options, i would populate another list with its appropriate sub category items.

IE

Header1 |
Header2 -> Selected | Sub Category1 Header 2
Header3 | Sub Category2 Header 2
| Sub Category3 Header 2

Hope that gives you an idea what im looking to do.

What im looking to create is essentially an ebay style category selector. So its likely that I will need to use ajax or something along those lines.

Drill down looks like what im after, but I cant use jQuery as it conflicts with the sites existing prototype libraries and I have no way of getting to work via noConflict in jQuery.

So if anyone knows of a Drilldown menu that uses prototype that would be great.
