How to add checkbox list to register user page?

Friday 07 January 2005 9:20:35 am

Hi -
I am using 3.4.4 and can't seem to find this anywhere........
I want to add an attribute to my user register page that will do the following ---
"Select all the units you are affiliated with..."
(checkbox)Unit A
(checkbox)Unit b
(checkbox)Unit c
(checkbox)Unit d

I see how to do it with a scrolling selection area, but would prefer to use checkboxes because they are easier than having to hold the control button for multiple selections.
What am I missing??????
Thanks for any help....
