Add-on Register-Form for 2 different Groups ?

[erich37]

I would like to have 2 different "Register Forms", based on User-Group.

So when a user registers, he needs to choose (via a Radio-button) to which Group he belongs to.



Example:
User chooses a "Radio Button" and by doing so, there are different "Custom Fields" shown:

Example:
User chooses a "Radio Button" (Supplier or Buyer) and by doing so, there are different "Custom Fields" shown:

Please let me know.
