I've created a content type 'Player' with the necessary fields. With the 'Inline Entity Form' module i've added this tot the default user registration form.
Now when a user register, he immediately creates a node for the content type 'Player'. And when he edit his user profile, he also edit the node.
Now I want to have the option, that a user can choose to register as a player or a coach. When a coach register, he should fill in other fields, and so create a node for the content type 'Coach' .
With which modules can I realize this?
