Display Rules in forms are very powerful, however they limited by the IF condition being limited to fields on the form.
If it were possible to include a Text Formula field within a Form or allow the Display Rules to reference a Text Formula within the IF conditions, it would open a lot of possibilities.
Use Case Example:
OBJECT for House
House: House 1
Pets Allowed?: YES
-
House: House 2
Pets Allowed?: YES
-
OBJECT for Tenant
Name: John Smith
-
OBJECT for House Tenant
House:
Name:
Type of Pet:
-
If a form is adding a record to the House Tenant object
- Type of Pet field for selection would be displayed if House 1 is selected
- Type of Pet field for selection would not be displayed if House 2 is selected
