Hi all,

I have a list of users belonging to a group: (user HABTM groups)

Group 1

- user 1
- user 2  
Group 2
- user 4
- user 2
- user 5  
Group 3
- user 6
- user 7

I want to enable user dragging between groups. Eg. i want to move user  
6 to group 1. The users are ordered alphabetically inside a group. If  
I drop a user in a group it would be ideal that it is thus placed  
alphabetically (not important though).

Can this be done?

Thanks  
Stijn
