Remove, rename, and change the drawing order of layers using the tools in the Organize group in the Layer tab of the ribbon.
Each layer you add to the map can be removed, with the exception of the basemap. Your map must contain a basemap, whether it is one of the default services from ArcGIS Online or your own. For more information, see Configure basemaps.
The order in which layers are listed in the Map Contents panel represents how the layers are drawn on the map. Within the map, the layers listed at the top will draw over those listed below them, and so on, down the list. You can easily move layers in the Map Contents panel to adjust their drawing order using the Bring Forward and Send Backward buttons on the ribbon.
In addition to setting the drawing order of layers, you can use transparency settings to further configure how layers display on the map. See Layer transparency for more information.
