LayerControl

Add a control to the map to show or hide layers.

m = folium.Map(tiles=None)

folium.TileLayer("OpenStreetMap", overlay=True).add_to(m)

folium.LayerControl().add_to(m)

m

Common layer arguments

Every layer element in Folium has a couple common arguments:

• name: how the layer will be named in the layer control.

• overlay: True if the layer is an overlay, False if the layer is a base layer.

  • base layer: only one can be active at a time. Tile layers are base layers by default.

  • overlay: multiple can be active at the same time. FeatureGroups and most non-tile layers are overlays by default.

• control: Whether the layer can be controlled in the layer control.

• show: Whether the layer will be shown when opening the map.

Next we'll give some examples using a FeatureGroup.

Remove from control

m = folium.Map()

fg = folium.FeatureGroup(name="Icon collection", control=False).add_to(m)
folium.Marker(location=(0, 0)).add_to(fg)

folium.LayerControl().add_to(m)

m

Show manually

m = folium.Map()

fg = folium.FeatureGroup(name="Icon collection", show=False).add_to(m)
folium.Marker(location=(0, 0)).add_to(fg)

folium.LayerControl().add_to(m)

m
