Marker with OpenLayers
The following examples shows 10 markers with the cluster feature enabled. All tt_address records have the same sys_category assigned with a marker icon. This category is selected in the ods_osm plugin settings.
The cluster feature is enabled and a cluster_radius of 60 pixels is set. You can click the clustered icon to zoom in or use the common zoom methods to show the markers.
Each marker is clickable and a popup shows the name, the address, a link to a website and an optional image.
Inside the layer switcher, you can disable the full cluster layer.
