Forms, fields and widgets

Plone includes several alternative form mechanisms

• Archetypes is used for content types in Plone 3.x
• zope.formlib is used for stock forms in Plone 3.x
• z3c.form is advanced form lib and available for recent Plones

You need to identify which form library you are dealing with and read the form library specific documentation.

Archetypes forms cannot be used outside content management. Please read more about Archetypes in Content section. This documentation applies only for form libraries.

Zope 3 schema (zope.schema package) is database-neutral an framework-neutral way to describe Python data models.
