This article covers merging multiple maps into one (creating a Map Mashup) with WP Google Maps. This documentation is current for WP Google Maps Version 6.
A Map Mashup allows you to join multiple maps into one map. You do this using special mashup parameters in your Map shortcode. Your shortcode for a Map Mashup will look something like this:
[ wpgmza id="2" mashup=true mashup_ids="2,3" parent_id="2" ]
Note: Make sure you remove the first and last space between the square brackets as shown above.
You will need to use the shortcode parameters below to create your Map Mashup:
The ID parameter is the ID of the Main Map (This MUST be the same as the parent_id – as shown in the shortcode example above.
Set as true to indicate you that you would like this map to be a mashup.
Include the IDs of all Maps you want to “mashup” in a comma-separated list.
The parent_id identifies the specific map from which the map settings will be drawn for the Map Mashup. In this case, whatever color or size is set for Map ID 1 will be used for the Mashup Map.
