Creating subforums listed under forum?
 

Ok, so it has been several years since I succeeded in doing this in 3.6, so here goes another in a long list of stupid questions I can credit to myself.

In a completely new 3.8.2 I can't seem to create subforums, (my terminology might not be right here)

So if I want a forum named "Ford Vehicles", and right underneath it, and within the same box, a multiple column stack of subforums that may say: Subforums- SUV's, Pickup trucks, Sports Cars, Vans, etc. how do I accomplish that?

An example is on vB's page here, under 3.8.vBulletin 3.8 Questions, Problems and TroubleShooting, right underneath it, within the came box is a subforum listing of vBulletin Quick Tips and Customizations"

Right now, all the vB presets are at default settings.

2 Forums below that on this site, where it says; "vBulletin Impex Import System " there appears a "Impex Bug Tracker" forum, BUT, it does not have the bold text next to it that says "Sub-Forums" like the above vB 3.8 Questions, Problems, etc" does.

How does one make the bold "sub-forums" text appear or not?

Thanks everyone.
