wForms is an open-source, unobtrusive javascript library that adds commonly needed behaviors to traditional web forms without the need for any programming skill. Supported behaviors are:

• input validation
• conditional fields (a.k.a switch/case)
• repeatable fields (a.k.a one-to-many fields)
• field hints (a.k.a. tooltips)
• computed fields (a.k.a. calculations)
• pseudo multi-page forms (javascript driven)
