This OpenStreetMap custom field plugin for Joomla allows your users to easily set one or more markers/areas/maps to any Joomla item (supporting custom fields (Joomla articles, contacts etc...). In edition mode, it shows a map the editor can click to set a marker. It can also click to have own current coordinates detected (if shared) and an address search field. It also has a area radius slider. In the front end , the plugin shows the map, marker and area as set with a fullscreen support. If you set multple occurences of the field, the plugin can render every each marker and area in the same one map. In that case the zoom setting is ignore and the map will land making sure every marker is displayed. The plugin uses OpenStreetMap so it does not require an API key, but Mapbox maps are supported with a Mapbox API key.
