I was expecting [Y].

I’ve read through the doc and couldn’t find this… So does the library support merging several ArcGIS feature layer and display as one single layer on client-side on the fly?
e.g. (a URL for a ArcGIS feature layer service would be) https://services6.arcgis.com/awdfawfwafawrawe/arcgis/rest/services/[project_name]/FeatureServer/1 So I can have several of these based on what the user toggles. (User could toggle to activate two layers or more) And I want to merge all the layers user selected, and display only one merged layer on the client side.

Or, what are the alternatives (don’t have to be client-side) to achieve this - “merging several feature layer and display as one layer on the fly”?

Thanks.

@jwasilgeo is right. you can use L.esri.DynamicMapLayer both to display and query features in more than one layer in a service.

Not that I am aware of but here are some alternative ideas:

1. Try to use the Leaflet L.LayerGroup to group your L.esri.FeatureLayer instances. Does this solve your use case?
2. If you have access to ArcGIS Enterprise MapServer layers instead (with “…MapServer/” at the end of the URL), you could use the L.esri.DynamicMapLayer and set its layers property.
