Adding Expand Widgets to same Div (JSAPI 4.x)

I want to add a bunch of widgets to a custom web app. Obviously, if there are a bunch of widgets in a single app, you run into issues of covering up too much of the map. Expand widget to the rescue.

 

The issue I'm running into is that I want to deliver a UI similar to what the Scene Viewer has going on with its expand widget, where every expand widget has been added to the same div.

 

I went through the samples and found that creating a new Expand Widget for each widget I want to add results in them being added separately with margin between each widget. The following code:

<!DOCTYPE HTML>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no">
  <title>Expand widget - 4.8</title>

  <link rel="stylesheet" href="https://js.arcgis.com/4.8/esri/css/main.css">
  <script src="https://js.arcgis.com/4.8/"></script>

  <style>
    html,
    body,
    #viewDiv {
      padding: 0;
      margin: 0;
      height: 100%;
      width: 100%;
    }
  </style>

  <script>
    require([
      "esri/Map",
      "esri/views/SceneView",
      "esri/widgets/Expand",
      "esri/widgets/Search",
      "esri/widgets/BasemapGallery",
      "dojo/domReady!"
    ], function(
      Map, SceneView, Expand, Search, BasemapGallery
    ) {

      var map = new Map({
        basemap: "topo"
      });

      var view = new SceneView({
        container: "viewDiv",
        map: map
      });

      // Create Search and BasemapGallery widget instances and set
      // container to a div element
      var searchWidget = new Search({
        view: view,
        container: document.createElement("div")
      });
      var basemapGallery = new BasemapGallery({
        view: view
      });
      // Create an Expand instance and set the content
      // property to the DOM node of the basemap gallery widget
      // Use an Esri icon font to represent the content inside
      // of the Expand widget

      var searchExpand = new Expand({
        view: view,
        content: searchWidget
      });
      var bgExpand = new Expand({
        view: view,
        content: basemapGallery
      });

      // Add the expand instance to the ui

      view.ui.add([searchExpand, bgExpand], "top-right");
    });
  </script>
</head>

<body>
  <div id="viewDiv"></div>
</body>
</html>

results in the following view.

 

I'm thinking I need to override the CSS and I found some sections in the API docs on doing that, but its a little heavy for a JS rookie like myself. How do I get the search and basemapGallery widgets into the same div similar to the first screenshot?
