Why don't you simply use AJAX?

You can use such code for the parent cat dropdown:

Code:
&lt;? foreach ($cats as $v) { ?&gt;

<option value="&lt;?=$v-Id;?&gt;">&lt;?=$v-Name;?&gt;</option>

&lt;? } ?&gt;

And then using AJAX (such as: http://www.prototypejs.org) you can add the "onchange" attr to the <select> field around the parent categories. That will then run a query, get the sub cats and put them into a second <select> below.
