Leaflet Markercluster

Provides Beautiful Animated Marker Clustering functionality for Leaflet using the Leaflet MarkerCluster library.

IMPORTANT!!!: since Leaflet 8.x-1.2, this Leaflet Markercluster (leaflet_markercluster) module has been embedded into Leaflet module itself, as submodule of it (located into the module subfolder). more info

Installation and configuration

First install the Leaflet module 7.x-1.4 or later and Leaflet JS library 1.0.2 or later, following the Leaflet README.
Then download the MarkerCluster library v1.0.0 or later from, say, https://github.com/Leaflet/Leaflet.markercluster/archive/v1.0.0.zip
The core part of the zip file is a directory named dist. Make sure this directory ends up in sites/all/libraries/leaflet_markercluster, so that the path to the essential javascript file becomes sites/all/libraries/leaflet_markercluster/dist/leaflet.markercluster.js

Enable the module. All Leaflet maps will now be using clustering out of the box.

If not, visit the Status Report page, admin/reports/status, for error messages.

This module does not itself have a UI to set MarkerCluster configuration parameters. However parameters may be set through javascript, Drupal code or other modules, e.g., IP Geolocation Views & Maps. Consult the README for details.
