PROBLEM
In ArcGIS Web AppBuilder, the transparency of an operational layer in a web app can be controlled using the Layer List widget.
However, the transparency changes cannot be saved, and upon refreshing the web app, the original transparency of the operational layer is displayed. In this example, the operational layer is opaque.
In a web app, the transparency of an operational layer is displayed according to the transparency of the hosted feature layers in the web map. Changing the transparency using the Layer List widget in the web app does not modify the transparency.
To change the transparency of an operational layer in a web app, change the transparency level of the hosted feature layer in the web map. Refer to ArcGIS Online: Set transparency for the steps to set the transparency for the layers. In this example, the transparency is set at 50%.
Refresh the web app in ArcGIS Web AppBuilder. The transparency of the operational layer is changed.
