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.
If you would like your form to be on your domain, you would have to get the source code for the form and have it embedded on one of your web pages hosted on your server.
You can get the source code for the form by following the instructions in this guide.
However, if you make any changes to the form via Jotform, it would require you to update the source on your web page for it to reflect the changes made.
You can also embed the form using the iFrame mehod, this would not mean the form is hosted on your server but it is more like a window to the web page the form is hosted on our server. This method would also require you to update the embed code if changes were made (adding or removing fields for example).
I hope this answers your question. Do let us know if further clarification is needed.
