Adding deeper subcats as links in cats on index page

[lankeeyankee]

Hi All,

I posted this in another forum, but I think that it is more appropriate here. Mods, please delete my post in the categories and products forum.

I'm trying to figure out how to add subcategories as text links under the category names on the second level index page. I have it set up to show categories on index page and I have the css flyout category menu sidebox installed. I am trying to save the amount of clicks when someone clicks on a category link on the main index page since some categories are 4 subcats deep. Ideally what I would like to accomplish is to have the main index page stay the same as it is with only the category name and image to keep it clean looking, and once one of the links is clicked the first level subcats that show on the next page will have any deeper subcats listed as links under the image. I have attached a screenshot of another site to show what I mean, imagine that this is the first subcat page that was reached from the homepage, and the user clicked on the category "drum parts" and this is where they landed.
If I am not clear enough please let me know and I will try to explain better.
Thanks!
Matt
