|In Joomla! 1.5, form fields were parameters. For that version, you may want to use the corresponding Helpsites parameter type.|
The helpsite form field type provides a drop down list of the help sites in your Joomla installation. If the field has a saved value this is selected when the page is first loaded. If not, the default value (if any) is selected. With the exception of the “Local” entry, which is always added, the list of help sites is generated from the file:
The 'local' string is translatable. The 'local' URL returned is an empty string.
Example XML parameter definition:
<field name="myhelpsite" type="helpsite" default="" label="Select a help site" description="" />
