I'm sharing an arcgionle map with basic viewer aplication.
I want to limit arcgis basemap gallery to 3 maps. I don't need ocean basemap and others, so I want to show only several ones.
I have see BasemapGallery Button example but I'm not sure how to implement it beacause in that one, it creatate map using json, and not map id.
Could someone give me any clue to this?
Thank you!
