hi!
i know i can add additional fields in sign up page. but can i make them of different type? i need a radio or select input for users to select a role

Hey! This is not possible to do easily as of now.

You may want to consider building your own sign up form in this case.

But we have an open issue about this which will make this easier to do.

An alternative could also be to ask the user the remaining things post sign up
