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.
Using the jotform, you are not able to do so. The users are offered a chance to review their answers/selections and submit only if they decide to do so.
Having that said, you can always grab the full source code of your jotform and include this option into the jotform's source code yourself, either by yourself or by hiring a developer to do that for you.
