Different types of profile, how to implement it correctly?

Question

Django

Good afternoon. It has its own Profile model (via AbstractBaseUser) .. it is necessary that when registering a user, the visitor can choose which type of profile (Individual, legal entity, store, etc.). Moreover, each type of profile can have subcategories, for example, stores are divided into pharmacies, shops, etc., and during registration, in the select "profile type" you need to display only "store", and in your account , the user himself chooses what kind of "shop" he has - shops, pharmacies, etc.
How to implement correctly and better.
Thank you.
