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.
To confirm, you like for your user to be able to save the filled out form to later complete it?
If that is the case, we have an auto fill feature that allows your user to save the information filled out to complete within a specific period of time.
Please note that the user will have to be using the same browser as well as not clear their cache for the information to be filled in when coming back to the form.
Please view on guide on how to set up the auto-fill option: http://www.jotform.com/help/227-How-to-Enable-Auto-Fill-Feature
I hope this helps, please inform us if you need further assistance.
