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.
Please be noted that when you create a form, you need to grab its direct URL or embed it in your webpage for users to be able to submit it online. Please check the screenshot below on how to grab your form's direct URL:
If you embed your form or share the direct URL to your users, they will see the fillable field and they will not be able to make any changes.
