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.
As I verify your JotForm now, the tabs seems to be working fine now.
It seems to be a temporary issue during the recent fixes being made with the widget. Apologies for the inconvenience this may have caused you. Please try clearing the browser cache and let us know if the issue still persists.
