Layers

open external class Layers(baseLayers: Control.LayersObject = definedExternally, overlays: Control.LayersObject = definedExternally, options: Layers.LayersOptions = definedExternally) : Control<Layers.LayersOptions> (source)

The layers control gives users the ability to switch between different base layers and switch overlays on/off (check out the detailed example).

Base layers will be switched with radio buttons, while overlays will be switched with checkboxes.

Note that all base layers should be passed in the base layers object, but only one should be added to the map during map instantiation.
