Link user goups with register Fields

Hi there,

I have a site where there are 4 user groups, there are common attributes and different ones.

What I need to do is a single register form, the user fills up the common fields and then he can choose between any of the 4 groups, when a user choose a group the different fields from the chosen group must be shown.

How can I achieve this?

Thanks in advance.

You can do that using CB Conditional. You'll need to create a select field for them to select a group. You'd then condition fields based off the value of your group field. Please see the below tutorial to get started.
