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 share to us the URL of your facebook page where you have used the form. We need to test the actual form on your facebook page to identify the issue.
We will wait for your response.
I have checked your form on different screen sizes and I can see it works fine, the form displays properly, I can see the current iFrame where the form displays is allowed to scroll so if the form has a higher than the iFrame it will properly display.
You could also provide us the details about the device or screen resolution where you notice the form gets cut off, we will be glad to further test on our end.
Looking forward to your response.
