US and Canada divided by regions
With Interactive Geo Maps Pro you can display multiple maps together using the overlay feature. You just need to create each map separately and then in one of them instruct to load the other one. We used this feature to create a map of United States of America divided by states together with the map of Canada divided by provinces and territories.
To achieve the result above you need to create 2 maps. One for the US and another one for Canada and create the interactivity you want in the regions or add markers. Once you have the 2 maps, you can edit one of them and in the ‘Overlay’ section simply select the other map. That map will now display both maps together.
You can set different colors and click actions for each individual state or marker in both maps.
There are several interactive maps plugins for WordPress, but for sure this is one of the features that sets this plugin apart from the others. Check out the full list of features available in the Pro version.
