How to save form and come back to it to complete the form at a later time?

1.) Can the people filling out our form save what they have worked on and then come back to it to complete the form at a later time?

Thanks!

Yes it is possible to achieve your requirement and there are multiple options available:

1. Auto Fill feature:  You can enable the "Auto Fill" feature of your form which will save the input data every few seconds. Please be noted that auto fill feature saves the input data in browser cookie. That means if the user access the form again from other browser, other system or clear the browser cache, the saved data will not be accessible.

2. Save input data in session: User can save the input data in session that is stored in our server. Please be noted that this feature requires two forms and the main form should have the "Page Break" field. The data is saved only on the click of the next button.
