Parameters are a mechanism in Joomla! 1.5 that enables administrators to configure Joomla! itself or its extensions. Parameters allow many aspects of the behaviour of Joomla or its extensions to be customised without requiring the user to know how to change the underlying code.
There are 21 different standard parameter types supported in the Joomla Framework for all extension types (templates, components, modules and plugins). This section gives a brief description of each parameter type, in alphabetical order. Full details of each parameter type are given on the following pages.
- calendar provides a text box for entry of a date. An icon next to the text box provides a link to a pop-up calendar, which can also be used to enter the date value.
- category provides a drop down list of categories from a given section.
- editors provides a drop down list of the available WYSIWYG editors.
- filelist provides a drop down list of files from a specified directory.
- folderlist provides a drop down list of folders from a specified directory.
- helpsites provides a drop down list of the help sites for your Joomla installation.
- hidden provides a hidden field for saving a parameter whose value cannot be altered directly by a user in the Administrator (it can be altered in code or by editing the params.ini file).
- imagelist provides a drop down list of image files in a specified directory.
- languages provides a drop down list of the installed languages for the Front-end or Back-end.
- list provides a drop down list of custom-defined entries.

- spacer provides a visual separator between parameter field elements. It is purely a visual aid and no parameter value is stored.
- sql provides a drop down list of entries obtained by running a query on the Joomla Database. The first results column returned by the query provides the values for the drop down box.
- text provides a text box for data entry.
- textarea provides a text area for entry of multi-line text.
