What is it?
Field Logic is used on Forms to either show or hide an upcoming section or field based on a previous selection.
How to Access
When you're building out a Form, you can start using Field Logic once you have at least one Selection Set field to base your logic off of.
In the above example, I don't need "If yes, please explain." to show up if someone doesn't have any dietary restrictions. Since the 2nd field is the one I want to impact, that's the one I'll select.
After clicking on the field you want, scrolling down through "Element Properties" on the left. Turn on "Enable field logic", and then hit "Edit Field Logic".
NOTE: If you turn "ON" Enable field logic, but do not make any selections, your Form won't function properly. This is because it's trying to find Field Logic that isn't actually set-up, so make sure you've finished your configuration!
Since I've checked off "Yes", my "If yes, please explain." field will only show up if a user has clicked on "Yes". If they select "No", they will not see the second field, and can simply proceed through the Form.
