How do I make a conditional field in Registration?

Hi
I want to make the registration form intelligent, offering fields to be completed dependent on the choice made in a drop down box.
The choices in the dropdown are:
Single Female
Single Male
Couples
Poly Group

I want to offer a different registration form dependent on the choice made.
Is this possible in CB?

Yes that's possible. CB Conditional can show/hide fields and even entire tabs based off conditions. As for the conditions there's a wide range of possibilities from simply checking if another field has a specific value or even conditioning with custom PHP. You can give this a try on our demo site below by clicking Administrator under the Login As module and taking a look at the backend (the demo site resets regularly so feel free to tinker around!).
