TreeLayerControl

Create a Layer Control allowing a tree structure for the layers.

See jjimenezshaw/Leaflet.Control.Layers.Tree for more information.

Simple example

import folium
from folium.plugins.treelayercontrol import TreeLayerControl
from folium.features import Marker

m = folium.Map(location=[46.603354, 1.8883335], zoom_start=5)
