Hey all,

I would like this to happen to the Categories Sidebox when customers navigate through the main and sub-categories.

1. At main page, top-level categories show
2. Click a top-level category then the sidebox only shows the sub-categories in that top-level category you just clicked.
3. When you get to the last sub-category, the categories sidebox changes to a completely different sidebox. Like, the cross-sell box or something else.

Can anyone give me some insoght on how to make this happen?

Take a look at how newegg.com handles their categories. Look especially close at their "Guided Search" sidebox. It is incredible and would benefit Zen Cart GREATLY.
