Leaflet MarkerCluster stop auto re-clustering when zooming

Question

When you zoom in and out, the markerclusters automatically "re-cluster", as in it calculates clustering again.

Is there an option for to disable the auto re-cluster when the zoom is changed?

Answer 1

Depending on exactly what you are trying to achieve, you might be interested in Leaflet.MarkerCluster.Freezable subplugin:

When frozen / disabled, clusters will no longer split / merge on map zoom, but retain their status as if they were on the specified zoom level.

For example if you want the clusters to reflect the zoom 15 configuration:

var map = L.map("map"),
  mcg = L.markerClusterGroup(options);

mcg.addLayers(arrayOfMarkers);
mcg.addTo(map);

mcg.freezeAtZoom(15);
