Overlays let the user see areas displayed on the map and also select points by their area. This option is not available for Area maps.

A map may have more than one overlay, and the user may switch between them.

Drag the Overlays that you want to include into the left box

The order in which they are set here is the order in which they will be displayed to the user.

The [No Overlay] option may be included to give the user an option to clear the map of all areas.

“Off” Overlays lets you decide whether to hide the locations from view, show them in subdued colours, or let the user choose the behaviour, when an area in an overlay is “Off”.
