Need function to group widgets.. pls read

Ok, the why I’m doing this is long to explain so I’m just going to get to the how…

This is how I need my widget markup output:

• Widget
• Widget
• Widget

• Widget
• Widget
• Widget

Basically, I need the output to group widgets divisible by 3 (whether it’s grouping by lists, divs or w/e. I just need to put a container around every 3 widgets.

Is there a way to put a container around every 3 widgets?

Thanks a lot!
