End-user authoring of multi-page form using Javascript and Php

I want to allow my users to create multi-page forms. So, on the basis of selection of for example a dropdown list of multiple choices, the user can author the multiple pages of the form itself and store the开发者_如何学Cir created forms in the server. The functionality similar to Google Forms in GDocs. Is there any example available?

Not really.

You might have a look at phpgem (which generates a form definition for a defined database) or phpmyadmin (again, this generates a form from a database - but on the fly). Or there's tools like phpeanuts, phplens and PfP Studio but these aimed at developers.
