We are building an Experience which include a web map with many layers. We would like to have several Map Layers widgets each only showing a part of those layers (sort of themed Map Layers). In WAB you could select which layers are visible and which are not. Is possible to cerate such a widget in EB Arcgis Online?
It is a workaround that I can not use. The goal of filtering the layers in the Map layers widget is to simplify it for the users. We have 1 webmap with a lot of information on different topics. We would like to show the layers per topic in a Map Layer widget. But at the same time we need to be able to show the different layers and topics in 1 web map to view possible clashes and interference.
Sorry to hear that it is not something you can use.
