Limit Forum Levels to Display

[ghinton]

I might be overlooking the setting, but is there a way to limit the levels of forums that are displayed?

For example:

Main Category
- Forum 1
- - Sub Forum 1
- Forum 2
- - Sub Forum 2

Is there a setting if I only want to show the category and the top level forums (ie Forum 1 and Forum 2), but not the sub forums (ie Sub Forum 1 and Sub Forum 2). I cant seem to find where to set the limit of how many levels it shows.
