Hi,
added multilang in google map:
https://maps.googleapis.com/maps/api/js?sensor=false&language={2-code lang}
Code:
$LangTag = JFactory::getLanguage()->getTag();
$LangTag =substr($LangTag, 0,2);
$doc->addScript('https://maps.googleapis.com/maps/api/js?sensor=false&libraries=places&language='.$LangTag);
Regards...
