The dropdown list with the COM_JSN_PUBLIC="Public" and COM_JSN_REGISTERED="Site Members" are not visible in most templates. From the standard Joomla templates, it only works in Protostar.
It does not work in Artisteer generated templates (like ours). There is no lable vissible either.
Could this be due to a conflict in classes: btn etc are quite common and most likely in use by the templates.
