I'm looking if there is anyway to combine a web form with the ability to set up a 'save' button and come back at a later time to complete a form and submit. Also for contingency purposes having the facility for forms to auto-save every minute for example. Does anyone know if there is anyway this could be integrated with something else to achieve this?

This would take a lot of custom coding not sure if it would be worth it. Every time you made a change to the form you would have to recode again.

I could be wrong here if someone else wants to chime in

Are you looking to use the form on a site that uses a login?
