Ajax register - multiple user groups

1- Ajax register -> Dashboard -> Options -> Groups -> Groups display
has two choices 1-list and 2-radio. Is it possible to add checkbox, for select multiple user group upon registration ?

2- Or rather flexible.
Suppose there are two groups, "students" and "teachers".
"Student" has subgroups of classes "501,502,503,..." from them should select just one.
"Teacher" also has those subgroups, but may choose more than one, additionally he/she should specify the teaching course  i.e. "maths, geography,..." one or more.

I suggest something like this...


3- And finally having different ajax-register forms (with different content and template) for different menu items.

Hi,

1) It's not possible currently.

2) Thanks, great suggestion but it's pretty complex and hasn't been much requested so far.

3) You can already create different registration forms with different custom fields and different registration group.
