I want to add a layer as basemap and it won't do it.

[PaulEntrekin]

I added a topographic map as basemap and it is not what I want. I can't get rid of it and when I try to add another layer (USA States) It says to click on the title and it will provide an option to use it as basemap.  This never happens.

I assume you have logged in using a valid ArcGIS Online Organizational account. Could you check if you missed anything in Choose basemap—ArcGIS Online Help | ArcGIS ?

Thanks Jayanta,

Most likely the cause of the issue being experienced is that the layer  (USA States) is a feature layer which is not a supported basemap layer type.

The following types of layers can be included in a multilayer basemap:

• Imagery
• Map image
• Tile
• Vector tile
• WMS OGC
• WMTS OGC
• Bing
• OpenStreetMap

If you have any questions about the layer type, feel free to share the service url,
