What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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.
Yes, you can do that by following the steps here: How to get the Full Source Code of your Form
Source Code option is great when you want to add any optimizations to your jotform directly, but if you make any changes to it in JotForm Builder, you will need to copy the code and paste it on your hosting again.
If you would like to have live version of code (see the changes as you make them). Then I would suggest using iframe embed option instead.
Do let us know if you have any further questions.
