Removing a layer
Each layer that 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 Configuring Basemaps.
You cannot remove or change the position of the basemap. It can, however, be renamed.
- Open the Map Contents panel. For instructions, see The Map Contents panel.
- Select the layer to remove.
- Click the Remove button on the Layer tab of the ArcGIS Map Web Part's ribbon:The layer will be removed from the Map Contents panel and from the map.
