I'm developing a registration form for our company and it has too many fields; I'm thinking of splitting the form into three separate forms (i.e. Contact Details, Skills and Services). I tried to link these forms together by pointing to a unique user_id field/variable in the first form however I need this linking to be done automatically and without the need for the user to select anything.The Skills and Services forms are stateless and would not store any data.Could you please advise what is the best solution to implement this?
