leaflet-layer-tree-plugin

Leafet.LayerTreePlugin

This plugin for Leaflet allows to switch layers on and off, structure them in a tree-like way

The list of layers to be displayed can be provided as a JavaScript object where each layer may look like as follows:

{
	"code": "osm",
	"name": "OpenStreetMap",
	"active": true,
	"selectedByDefault": true,
	"openByDefault": true,
	"childLayers": [],
	"selectType": "MULTIPLE", // "SINGLE", "NONE"
	"serviceType": "OSM", // "TILE", "WMS", "WFS", custom.
	"params": {
		"url": "http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
	}
}
