BasemapLayerListWidget Class
The Basemap ListItem class represents two of the operational Items in the LayerList ViewModel. In the Basemap
LayerList widget UI, the list items represent any base or reference layers displayed in the view. To display the
ListItems as separate types, a developer will need to specify a base or reference. It provides access to the
associated layer’s properties, allows the developer to configure actions related to the layer, and allows the
developer to add content to the item related to the layer.
