How can I build signup form for user it consists of three forms. first form is basic login info, second form can have multiple instances of single form where the user can add more form or remove it. and third form if nested from where user also can add from or remove it. all these in under single submit button

I have been looking at the documentation and thought maybe inline-formsets would be the answer. But I am not entirely sure.

Currently, I have built two different forms. second form with 'formset_factory' function using that we can create multiple instances of single form. now question how can I build third form with nested form feature and then how to fetch them inside single template.
