[fw-mvc] Zend Form with Multiple Columns

I understand the concept of creating multiple columns in a Zend Form, but I really don't know how to create the subforms, and the display groups to do so. I can't really seem to find any examples on the web, and I think I could figure it out if I had a little extra information. I've been searching Google for a couple of Days now trying to solve this problem, and I can't seem to find any example of anyone actually creating a form with 2 columns. Any help would be very much appreciated.

Thomas
