Dynamic icon clustering

Icon clustering groups any marker icons that overlap on top of each other. The purpose of icon clustering is to simplify a map interface and improve map performance.


When icons overlap, CMaps Plugin and GMaps Plugin will automatically group them together and indicate the number of locations that are grouped. As you zoom in the map, the clustering feature will automatically break these locations apart when they no longer overlap.

Runtime Enable/Disable

In CMaps Plugin, an additional property is available to dynamically enable/disable clustering using a single toggle property. The Cluster Markers property should be bound to 1 cell. Use the values “0” and “1” to toggle the clustering feature.

Disabled functionality when using clustering

As of GMaps Plugin 3.5, using marker clustering will temporarily disable the following features to ensure consistency for legacy versions of GMaps Plugin and migration.

  • Alerts
  • Bound Marker Colors
  • Bound Marker Types

Cluster icons and selector destination

When an icon is selected as a cluster, you can utilize selector destination property to capture all of the locations, so they can be utilized in a list or calculation. This multi-selection functionality is does NOT require you to enable the multi-selection property on the General Tab. Make sure you bind a range of cells in the destination range if you are using clustering.
