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.
Our developers have updated the HTML/Email editor (TinyMCE) several days ago, so in general, the HTML customization should be more stable now.
If you are facing any issues with updated editor, please let us know and we will try to investigate it further. Thank you.
