title: How to add background image in material-ui drawer component
body: <p>I have tried these two methods, but neither work.</p>
  
  <p>Method one: change Drawer component directly.</p>
  
  <pre><code>    &lt;Drawer
        style={{backgroundImage: url('../../public/images/sideList.jpg')}}&gt;
        &lt;div&gt;
          &lt;SideList/&gt;
        &lt;/div&gt;
      &lt;/Drawer&gt;
  </code></pre>
  
  <p>Method two: add background-image property for a nested div.</p>
  
  <pre><code>    &lt;Drawer&gt;
        &lt;BackgroundImageDiv&gt;
          &lt;SideList/&gt;
        &lt;/BackgroundImageDiv&gt;
      &lt;/Drawer&gt;
  </code></pre>
