I would like to display only the subcategories for a category in a left sidebox. So, basically, you click on a category (horizontal top menu which I have working just fine) and on that specific category page the subcategories are listed in a sidebox and the first subcategory's product items fill up the center column.



There are a lot of posts related to sideboxes, menu trees etc but after hours of reading through and trying a few I still can't seem to figure it out.

Any help, links to solutions in the forum, etc. appreciated!
