OpenLayers LayerSwitcher

Forked version of Matt Walker's Layer Switcher: https://github.com/sookoll/ol3-layerswitcher

Froked and modified to work with openlayer 5 (ol@5.3.0)

How to setup

var layerSwitcher = new ol.control.LayerSwitcher({
tipLabel: 'Legend', // Optional label for button
onOpacityChange: function(opacity, layer){
console.log("Do something")
},
onLayerToggle: function(visible, layer){
console.log("Do something")
},
layers: [{
title: "Overlays",
layers: [
{
title: "Layer One",
layer: layer_one,
enableOpacitySliders: true
},
{
title: "Layer Two",
layer: layer_two,
enableOpacitySliders: false,
legend: "Something about layer"
}
]
},
{
title: "Base Layers",
layers: [
{
title: "Base One",
layer: base_one,
enableOpacitySliders: true
},
{
title: "Base Two",
layer: base_two,
enableOpacitySliders: false
}
]
}]
});

//Add filter legend
this.map.addControl(layerSwitcher);
