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.
I think you will achieve this with a custom thank you page, for example, instead of showing a thank you message after a submission, you can simply load the form again.
You only need to provide the link where your form is located on and that should be all, here is also a guide that will help you with detailed info about this: Redirecting-Users-to-a-Different-Page
If you have any question, please let us know.
