The idea is to create "Rule Based Logic" (RBL) for submitting of form fields, and is something highly requested by L'Oréal teams in which Studio has to add custom each time.
An example of this RBL is a L'Oréal brand might be collecting SMS from consumers for text marketing, which specifically requires additional legal language, and a consumer has to check a checkbox. The idea is to make the checkbox mandatory to be checked ONLY if a user has entered a value into the Phone Number field. If a user doesn't enter a phone number value, then they can still submit their email without checking the phone number checkbox.
In short, if someone enters a phone number, they are required to check the checkbox, if they don't enter a phone number field, they can submit without checking the checkbox. This is what is typically implemented custom by Studio.
