How to do sortable within a sortable?


I'm trying and I'm getting mixed issues.
Essentially I have this structure loaded from the db
Section 1
Question 1
Question 2
Section 2
Question 3
Section 3
Question 4
Question 5
Section 1, Section 2, and Section 3 are all dynamically set in the
"connectWith" each other...
I would like to be able to drag Question 4 to Section 2 if desired...
I'm not getting this behavior from my site... any ideas?
