All those little location markers on the map that Google just made FAR more prevalent in their latest update? Those are what they call map icons. They are also clickable which means all those locations will pop up a map bubble even if they are not YOUR Locations for your business. Premier Add On 4.7.1 for Store Locator Plus lets you disable the “clickability” on the map icons.
The Category Manager section provides a full management interface for Store Categories. This is where you will add new categories, determine if you want them to be a parent or a child , rank the category (optional) in the extended data, add a medium icon and/or map marker.
