JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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.
So you mean that you want to have your jotform sort of reset itself to go back to the empty form after seeing the thank you page when someone submits on it.
To do this simply get your forms url "https://www.jotform.com/51035300858954" and add it as a thank you page url to redirect them back to it again.
See this guide here https://www.jotform.com/help/38-Redirecting-Users-to-a-Different-Page for a more detailed explanation.
