LayerList - Layer Reorder with Dynamic Workspaces

Question

Hello,

I noticed that the LayerList widget does not allow to move layers even if the underlying map service has dynamic workspaces - allow per request modification enabled. 
Is there an easy way to fix this? I started poking around with the PopupMenuInfo.js class in the LayerList widget and noticed that "FeatureLayer" types do not have this option. So I duplicated the Widget and tried to add it in but it shows up as a disabled menu item. I did some further digging and noticed that the logic for this is true since Move Up and Move Down by design is only available for RootLayers not individual layers in a service.

Any idea on the proper direction to take here? Has anyone done this before ?

Thanks in advance,

Prem

Perm,

No, you are correct in that understanding.

Robert,

Thanks again for the attempt to clarify. Maybe I am missing something here.

If I have two FeatureLayers I can control which FeatureLayer is displayed on top, just as if I had two Graphics Layers. So essentially since all my layers are treated as individual FeatureLayers in WAB instead of a Dynamic Service, I should be able to control the order.

I get what you are saying that FeatureLayers/GraphicLayers are drawn above all else, but the order of those can be controlled if there are more than one of those at the top. So if I added 2 graphicsLayers to a map, the one added last would be at the very top.

If I am not understanding this correctly in reference to WAB would you elaborate?

Cheers

Prem,

No you are missing what I am saying. FeatureLayers and GraphicsLayer will always be drawn above other layer types and there is nothing you can do to change that, it is a limitation of the 3.x JS API.
