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 have you tried so far? Your post isn't very clear, to be honest.

Sounds like you are looking for a way to present a hierarchical/tree structure as a navigation page element.

I don't know how advanced your PHP skills are but you might look at Zend_Navigation component from the Zend Framework. You don't need to use the whole framework, most of the components are "use at will".

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.

You want a drill down list basically.
If this was single selects per 'level' I'd do this by presenting the root level in a <select> list on the page then add an 'onchange' call to a JavaScript function which uses AJAX to call a php page passing the chosen parent ID. This page would get the sub levels from the db and load a new <select> box with the values. The output is returned to the AJAX JS function and you can drop it into a waiting DIV container on your page. With a bit of tweaking to the JS function, you can repeat for multiple 'levels' in the heirarchy.

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.
