How to display registration form fields based on the taxonomy term?

Question

I have three taxonomy terms. And I want to display different fields in the registration form based on the taxonomy term.

I want something like this.

taxonomy term 1:
Registration form fields: Name, Email, Password, City, phone

taxonomy term 2:
Registration form fields: Name, Email, Password, Country

taxonomy term 3:
Registration form fields: Name, Email, Password, State, phone

Is it possible? if yes then please guide me.

Answer 1

On Drupal 7 you've a new API named State API. You can use it to hide or show your fields.

Answer 2

I think we can try with combination of two module.

1. field_collection
2. conditional_fields
