Losing progress on a partially created form is bad. Make sure to save your work frequently as you’re creating forms. But if you forget to save your work, Liferay Forms has your back.
By default, a form is auto-saved every minute. You won’t notice anything in the form builder while the back-end auto-saves the form. You can change the auto-save duration in Control Panel → Configuration → System Settings → Forms (in the Content and Data section). To disable auto-save, set the interval to 0.
For unpublished forms, an auto-save works just like a manual save. For a published form, however, auto-saved data isn’t automatically propagated to the form. You must click the Save button in the form builder to publish the changes.
