Smart Map cluster marker I use Smart Map for a project, but I have a question for this plugin.

Is it possible group the markers per cluster or I need see other options.

Tks
Yes, it's definitely possible to cluster your markers with Smart Map.
In fact, anything that you can do with the Google Maps API can also be done with Smart Map:

Manipulating the map in JavaScript

I'd recommend adding the Marker Clusterer JS library to your project.
