The Map Contents pane is a central component of the Esri Maps Web Part. The Map Contents pane displays the list of layers contained in the map, and you can use it to toggle layer visibility on and off. By default, the pane also shows the symbols used for each layer.
Map Contents configuration options include specifying which layers to include in the Map Contents, whether to allow end users to change layer visibility, and the ability to show only the layers visible at the current scale.
