CMS Sections & Category Manager Question:
 

Hi, I am trying to add a sub-Category, but doesn't seem to want to do that I am almost certain it's a limitation by vbulletin but wanted to may sure I wasn't doing something wrong.

Here is an example of what I am trying to do.

Section

Category
Category
Category

Sub-Category

Reason behind this is I am using the program name as a section then the section information as category (because i only want those category to show when inside that section) and then I have an add-on category which would also have add-on names so that the developers can release release press release articles about that add-on.

Anyway to accomplish this?
