I'm testing out the LayerList javascript widget. Is there any way to group the layers?
var layers = [ { layer: new FeatureLayer("http://ourserver/arcgis/rest/services/ourcommune/commune_base/MapServer/1") //featureCollection: featureCollection, // required unless layerObject. If the layer is a feature collection, should match AGOL feature collection response and not have a layerObject. showSubLayers: true, // optional, show sublayers for this layer. Defaults to the widget's 'showSubLayers' property. showLegend: true, // optional, display a legend for the layer items. //content: , // optional, custom node to insert content. It appears below the title. showOpacitySlider: true, // optional, display the opacity slider for layer items. //button: , // optional, custom button node that will appear within the layer title. visibility: true, // optionally set the default visibility id: "Commune_Cadrillage" // optionally set the layer's id }, { layer: new FeatureLayer("http://ourserver/arcgis/rest/services/ourcommune/commune_assn/MapServer/3") //featureCollection: featureCollection, // required unless layerObject. If the layer is a feature collection, should match AGOL feature collection response and not have a layerObject. showSubLayers: true, // optional, show sublayers for this layer. Defaults to the widget's 'showSubLayers' property. showLegend: true, // optional, display a legend for the layer items. //content: , // optional, custom node to insert content. It appears below the title. showOpacitySlider: true, // optional, display the opacity slider for layer items. //button: , // optional, custom button node that will appear within the layer title. visibility: true, // optionally set the default visibility id: "Commune_Main" // optionally set the layer's id } ]; var layerList = new LayerList({ map: window.myMap, showLegend: true, showSubLayers: true, showOpacitySlider: true, layers: layers },"layerListDom"); layerList.startup();
This shows up as:
- Commune_Cadrillage
- Commune_Main
How can I get this to be :
- Commune
--Commune_Cadrillage
--Commune_Main
