The Map & Contact is used to display a location of the Review i.e. the location of a Castle on a map or the address as text or both.
To display and pin a location on the Map you will need to supply a location via longitude and latitude to be the most accurate, or the address with Postcode.
By entering the address details you have the option to display them as Contact Details as well as a Map Location.
To add Map & Contact to a Review Type make sure to check the Map & Contact checkbox when creating a Review Type.
If you have already created the Review Type then you can add the Map & Contact by Updating that Review Type.
