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.
To better assist you, can you please share the form's URL or the link where you embed it? I'm unable to find any accounts associated with the email you used here in the forum.
For the meantime, you can try making the form responsive if it is not enabled. You can enable it under the "Designer" options.
If you embed your form into a website, please try using the iFrame code instead, here's the guide: Getting the iFrame Code. Please do make sure that you remove the <script> code associated with the copied iFrame code with us, this might cause conflict with your other script codes.
I hope this helps. Let us know if you need more assistance.
