Binary Blue Support

Hello,

Im running the binary blue theme on wordpress 2.0.2 on a hosting server. The theme is beautiful, and I don’t want to lose it. It’s available here: http://www.4null4.de/wordpress-binary-blue-theme/

The problem is – I need a way to fold my categories: see howtobewebsmart.com. I’m trying to install the fold category plug-in, but have no idea as to which category file I need to edit, or how to do so.

I’m desperate!!! If fold category is not the way, what is the best collapsible tree navigation system that will work with this theme/version of wordpress??? Nothing I’ve tried has worked so far. My goal is to have users of my site rarely ever scroll…
