Fields - Location
The Fields - Location plugin offers a Google map location selector as a custom field type. Using this plugin, you can add any number of map fields to your articles, categories, contacts and/or users.
The plugin configuration offers only 2 options, Google Maps API key and Google Maps Static API key. The field configurations are made on a per-field basis. You can choose sizes, default location, map type, zoom level and you can choose the display to be either a Google map, a static map or a latitude/longitude textual display.
A user named "Reinhard" suggested that I add Google Places Search to the editor - so I did! You can now search for your location to speed up the process and find those hard to locate places!
I needed this for one of my projects, and I thought the community would benefit from it as well.
I build custom extensions - let me know what you need!
