The helpsites parameter type provides a drop down list of the help sites in your Joomla installation. If the parameter 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:
<param name="myhelpsite" type="helpsites" default="" label="Select a help site" description="" />
