The WPSLP Experience Add On and MySLP Professional support the Google Map Style rules. These rules let you control the “inner style” of the map itself. Pre-defined map rules allow you to set a variety of styles via the map settings on the SLP admin panel.
For MySLP go to Store Locator Plus > Settings > Map > Map Style
For WPSLP go to Store Locator Plus > Settings > Map > Map Style
The value of this entry is a Google Maps JSON style string. Some of our Plugin Styles in the Style Gallery will set this for you. You can also build your own with services like Map Style With Google.
