Anchor to Best PracticesBest Practices

  • If your MapMarker components are interactive, make sure that the selected marker's icon is different from the rest of the non-selected markers.

  • If there are a large number of MapMarker components obscuring important features of the map, set them to clusterable to help increase the readability of the map.
