Use the top right Layers Control to dynamically add / remove Layer Groups from the map. Notice that child markers are actually added to / removed from the Marker Cluster Group!
This is the standard Leaflet Layers Control.
Note: it is normal that the computed clusters depend on the order of insertion. This is a result of Leaflet.markercluster algorithm.
This example is directly adapted from Leaflet.markercluster
The only difference is that markers are added to 4 different
subGroup's which are bound to the MarkerClusterGroup, instead of markers being directly added to the MCG.
