Can I make the first name required and the last name optional on the Full Name field?

Is this possible? Thank's in advance!

Sadly, that's not possible. The FULL NAME field is treated as a single field so if you set it as REQUIRED, both first and last names will be required (and vice versa).

If you need them to be treated separately, you have to use the SHORT TEXT ENTRY (textbox) and add 2 of them:

1. One that will act as the first name (set as REQUIRED)

2. And the other one will act as the last name

Thank you!
