This sample demonstrates how to add a Legend widget instance to a LayerList widget. This is done by adding the legend string to the panel of the appropriate ListItem in the LayerList widget.

// Add a legend instance to the panel of a
// ListItem in a LayerList instance
const layerList = new LayerList({
  view: view,
  listItemCreatedFunction: function(event) {
    const item = event.item;
    if (item.layer.type != "group") {
      // don't show legend twice
      item.panel = {
        content: "legend",
        open: true
      };
    }
  }
});
view.ui.add(layerList, "top-right");
