I am having an issue with my layerlist widget background being slightly transparent. I would like to set the background opacity for the widget to 100% so that the map cannot be seen behind the layer selection.
I'm using WAB dev ed + the foldable theme. I've looked through the widget documents to try to find a setting for this, but am having trouble locating it. Can anyone point me in the right direction? The only transparency settings I can find seem to be for the individual layers.
