title: How to remove fields from parent form?
body: <p>I have a form that I use to register users. I have another form that I use to login users. These two forms share common properties such as the username and password.</p>
  
  <p>I tried to create a LoginForm that inherits from RegisterForm but I don't know how to remove fields I don't need for login, such as repeat password or the agree to T&amp;Cs checkbox.</p>
  
  <p>How can I do this? These forms inherit from Form not ModelForm.</p>
