I can't really explain this very well, but if you take a look at my forums here:

http://www.jonwatson.ca/blog/modules/newbb/

You will see that the Main Options show up as a list rather than a drop down box:
Main Options
Main Options
Mark all forums read
Mark all forums unread
View all topics
View Digest
View unreplied topics
View unread topics
Admin CP

The problem with this is that it creates an abnormally high header on top of the forums which, while functional, is ugly.

I think this is supposed to be a drop down list, no? Any ideas what I'm doing wrong?

Thanks!
