The Form Assembly – Free Web Form Builder, Form Templates and CSS Stylesheets.
The Form Assembly is a two part project: the wForms extension and the Form Builder.
wForms is an unobtrusive javascript extension that adds commonly needed behaviors to traditional web forms. It is cross-browser compatible, and does not require any knowledge of javascript to be used. Implemented behaviors are: Switch, Repeat , Field Hint and Form Validation.
The Form Builder is a tool for creating standard compliant web forms. It integrates the wForms extension and relies on a set of technologies like XML, XMLHttpRequest, XSLT and DOM (a.k.a Ajax) to provide a seamless single-screen experience.
