Controls

Leaflet controls are UI elements anchored to the corners of a map (zoom, scale, custom buttons, etc.). Folium exposes a generic Control class that can render any L.Control.<Name> class. This is useful when you want to wire up a Leaflet plugin directly in user code without creating a new folium.plugins class.

Built-in controls

m = folium.Map(location=[45, 0], zoom_start=4, zoom_control=False)

Control("Zoom", position="topleft").add_to(m)
Control("Scale", position="bottomleft").add_to(m)

Leaflet plugin controls

If a Leaflet plugin exposes a L.Control.<Name> class, you can wire it up directly and attach its JS/CSS assets to the map.

import folium
from folium.features import Control

m = folium.Map(location=[45, 0], zoom_start=4)

control = Control(
    "fullscreen",
    position="topright",
    # Any plugin options become JS options.
    title="View Fullscreen",
    titleCancel="Exit Fullscreen",
)

# Add the plugin's JS/CSS assets.
control.add_js_link(
    "leaflet-fullscreen",
    "https://unpkg.com/leaflet-fullscreen@1.6.0/dist/leaflet.fullscreen.umd.js",
)
control.add_css_link(
    "leaflet-fullscreen",
    "https://unpkg.com/leaflet.fullscreen@1.6.0/Control.FullScreen.css",
)

control.add_to(m)
m

For reusable plugins, consider creating a dedicated folium.plugins class. For one-off integrations, Control keeps the wiring minimal.
