How Do I Merge Multiple Maps into One?

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.

Mashup IDs

Include the IDs of all Maps you want to “mashup” in a comma-separated list.

Parent ID

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.

    I can not make this work. I have two maps I can see separately when used in a page, but when I try to join them, nothing is shown.
    I use this syntax: [wpgmza id="3" mashup="true" mashup_ids=”2,3″ parent_id=”3″].
    Please help.

      It looks like you are using the wrong double quotes there.
      Try using ” instead of ”

        Many thanks for answering. I’m not sure I have two different kinds of double quotes on my keyboard, but I can see the difference in your expression.
        But, if I copy/paste your expression [wpgmza id=”1″ mashup=true mashup_ids=”1,2″ parent_id=”2″] and substitute the number 1 for the number 3 (as my maps to mashup are 2 and 3) no mapa is shown.
        Thanks again.
