Hello good day.
I have added a sub-grid in the form (Account) referring to the entity (Contact), and I get this form:
when performing the action of adding a new record (Contact), a form is placed at the top
This way you add contact records.
My question is how could I do that same way for other entities that I have (custom entities), because I can't get the new registration form to be placed that way, I only get it to be placed in this way.
