There are a number of URL parameters defined in the WMS standard, including layers. ArcGISOnline chooses not to let you specify them in the layer configuration, but the user should be able turn them on or off if the WMS Itself is configured to allow that.
"Control which OGC WMS layers appear in your map When you add an OGC WMS layer to a map, all the layers in the service get added to the map, but only the first layer appears in the map. To turn on the other layers, click the Contents button, click the OGC WMS layer name, and check the boxes next to the layers you want to appear in the map. When you add an OGC WMS layer as a basemap, the first 10 layers in the service are added and all 10 layers appear visible. You can control which layers in your OGC WMS appear on the map by default by first adding the OGC WMS to ArcGIS Online and using the Search for layer option in the map viewer to add your layer to the map. When you add the layer as an item in ArcGIS Online (through My Content), you select which layers you want to include and these layers automatically appear on the map when you add the OGC WMS to the map." --ArcGISOnline help Joshua Lieberman josh*at*oklieb*dot*net > On Jan 29, 2014, at 3:01, Alex Mandel <[email protected]> wrote: > >> On 01/23/2014 11:29 PM, Mick Wilson wrote: >> Hi.
