You have a lot of different markersets defined by several settings (categories, filters, ...), and you want to allow the users to select them...
Check / uncheck marker selectorsTry it !
The markers are from Sobipro.
In this map we inserted 3 markersets with the category dependent icons.
Each markerset is based on the main category including each child categories.
There is also a version of this toggle selector that check only the first markerset.
The toggle selector and the optional icon are 100% automated.
