Standard form field and parameter types
From Joomla! Documentation
There are many different standard parameter and form field types supported in the Joomla Framework for all extension types (templates, components, modules and plugins). This section gives a brief description of each form field type, in alphabetical order. Full details of each form field type are given on the following pages.
Form fields and the JForm class were introduced in Joomla 2.5. Prior to that these standard types were referred to as parameter types and were handled by the, now deprecated, JParameter class.
