Although that might be possible, as Ronald Catersels mentioned, with a plugin, Leaflet Maps are using OSM (Open Street Maps) style maps that have no functionality other than just showing a map. I have some features planned for this widget, but due to time pressure on other projects I will probably start implementing these in Q3.
If you file a request on Github, we might look into it. If there are any javascript/widget developers that want to create this functionality and can provide a pull request, that would be awesome.
