Leaflet layer control with support for grouping overlays together.

Demo

Add groupings to your overlay layers object, and swap out the default layer control with the new one.

var groupedOverlays = {
  "Landmarks": {
    "Motorways": motorways,
    "Cities": cities
  },
  "Points of Interest": {
    "Restaurants": restaurants
  }
};

L.control.groupedLayers(baseLayers, groupedOverlays).addTo(map);

The example shows some basic CSS styling of the new control elements.

This plugin only affects how the layers are dislpayed in the layer control, and not how they are rendered or layered on the map.

Grouping base layers is not currently supported.
