Hopefully this is a simple fix that I am just overlooking. As the subject states, I want to limit how deep the subcategory listing goes to just one level. Reason being is that each subcategory (level 1) has at least 20-30 categories after it and that would just make the sidebox look a bit crazy. If it was less, that would be a different story.

I read on a previous post that someone just suggested breaking it up a bit more...which would work, but basically I am dealing with a comic book store with a long list of titles so there is still some necessity for a subcategory with many many categories below it.

An example of what I am trying to do:

-current-
Manga
-English
-multiple categories for each series or for a single alphabetical letter
-Japanese
-multiple categories for each series or for a single alphabetical letter

-what i'm trying to accomplish-
Manga
-English
-Japanese

One solution I've thought of was to just turn off subcategories listing under layout settings, but I still prefer to have at least the first level listed. If this can't be done, then I guess I can live with that, but hopefully someone knows what I should edit to get the ideal setting right. :)
