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.
Please be noted that the tab widget works with the page breaks on the form. Since you have only 3 page breaks on your JotForm, i.e., making the form to 4 pages you are allowed to have only 4 tabs. The additional tabs will not be displayed when the number of page breaks are not matching. If you want to have more tabs on the form, you'll need to place additional page breaks on your JotForm as required.
Hope this information helps. Thanks!!
