NodeMapWidget

Module: UI

This widget localizes a node in a small map and it can also show, when available, the Google Maps layers or the Openlayers 3 layers associated to the node. See mode option for more info.

The map is realized by default using Google Maps API and gmaps.js. The map can be realized using Openlayers 3 also.
