Hi.
New version of plugin can show markers from different maps.
You can call map with
{zhgooglemap-group:NNN;MMM}
where NNN – group id
and MMM – map id
{zhgooglemap-category:NNN;MMM}
where NNN – category id
and MMM – map id
I’ve corrected component to show group id
And I’ve change version of used marker clusterer plus to 2.0.5
