Display sublayers in group layer

Question

I would like to expand sublayers when the map starts.

I set sublayers and expanded to true but do not see changes.

I wonder if I misplaced or used the incorrect code.

        layerControl: {
            include: true,
            id: 'layerControl',
            type: 'titlePane',
            path: 'gis/dijit/LayerControl',
            title: i18n.viewer.widgets.layerControl,
            iconClass: 'fa-th-list',
            open: true,
            position: 0,
            options: {
                map: true,
                layerControlLayerInfos: true,
                separated: false,
                vectorReorder: false,
                overlayReorder: false,
                sublayers: true,
                expanded: true,
            }

Answer 1

sublayers and expanded are specific to each layer not the widget. These options should be placed within the layerControlLayerInfos for the layer. Here's an example. These and other options for the layerControlLayerInfos are listed in the CMV documentation.
