If two markers of this type would overlap, the one with the higher `zIndex` is shown. If they have the same `zIndex`, the one with the lower vertical screen position is shown.\n\nThe following example shows setting collision behavior for a marker: \n\n const marker = new Marker3DElement({\n position: {lat, lng},\n collisionBehavior: google.maps.CollisionBehavior.REQUIRED\n });"]]
