AbleCommerce Shopping Cart Software

Hey all, here is what I am wanting to do. I am going to be using the category list for my new site design. Currently, the Category list displays only one sub category at a time. See photos below. What I want to do is, when someone clicks on lets say, Adapters and Connectors from my menu, instead of then having to click a sub category, I would like the category list to display all sub category in a category down the page, on the same page and still be seperated. So for example ; the adapters category has sub category's named 3.5mm adapters, coax adapters, and dvi adapters. I would like the category grid to output:

3.5mm
_______________
Category Contents listed as Category List


Coax Adapters
_______________
Category Contents listed as Category List


DVI Adapters
_______________
Category Contents listed as Category List

See, if you look at the 3rd image below - you will see currently you have to select a sub category - I would like to be able to display all of the items on the main category page, and only show individual sub categorys if they click that link from the menu.
Thanks for the help!

Bump still need this done, will pay good $ to have by the 5th.
