Hello! I'm trying to customize the widget layerlist web AppBuilder. I need to make the sublayers have the option of transparency as it appears from the submenu to the root layer.
I managed to figure out how to make the transparency option appeared with the slider for each of the layers. For this, I changed the PopupMenuInfo.js file "itemInfoCategoreList" variable, adding a new key {key: 'transparency'} for the 'FeatureLayer' array.
The problem is that I do not know where I need to change to make this functionality be effectively executed. Making a debug by google chrome, I realized that "if" is not run down to the sublayers, if the line (this.layerObject.setOpacity) always returns undefined:
