How to make drop-down menu with subforums links?
Can't see it in config settings.

If we go to any forum which have subforums, then we want to see in upper menu drop-down similar to "quick links" with lists of subforum of this forum.
Or something like this. Had seen it several times, but digging out through config settings we were unable to locate place there to switch it on.

It's possible this is a file modification -- if so, you should try looking at vBulletin.org, the official hacking site for vBulletn .
