What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
We don't have this feature, but our conditional logic should be easy enough to configure since all the fields are in order in the dropdown selections.
Anyway, here's a workaround - add the Form Collapse Field and put your names there:
Just make sure to select: Visibility to Hidden and Status to Open
Also, put a break collapse right before the submit button so to make the last section open and visible.
