Get All Entity Specific Form Fields

Hi,

How Can I just Get All Entity One Form Fields ?

For Example;

Entity = contact

Form1 = Efective Contacts + Related Fields {Name, Surname, E-Mail }

Form2= InactiveContacts + Related Fields{ Adress, w1, w2}

On The Form Of Fields Output = Contact => InactiveContact's => Adress, w1, w2
