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.
We support long forms, but I would honestly tell you that the longer the form you have, the speed of the form will be affected. Sometimes, the form will freeze up on loading and submit depending on the functions that are enabled to the form. Because everything needs to be loaded first in order for the form to work properly, such as the scripts.
I would suggest breaking it down to multiple forms instead of a single form with multiple pages so just to make sure everything runs smoothly.
