Create record in a collection when signin up

Hi,

I need to create some records in a collection (which is not the collection “Users”) when the user is signing up and link them to another collection with a relationship. How can I do that? I can’t link collections together without displaying a list, but I don’t want to display anything.

Do you have an idea?

Any idea?

When I want to add an action to the “submit button” of the sign up form, it doesn’t work because the user is not already logged in.
