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.
This happens only when you've added a page break button to your form, this is to avoid users to scroll up to continue filling out the form, so they're automatically redirected and can simply continue filling out the form.
If you're using the direct link of your form then you could add the "?nojump" parameter so this effect is removed, example: https://form.jotform.com/70545382654965?nojump
If you've embedded the form in a website then you can add it at the end of the link in the embed code.
Hope this helps.
