title: Show only part of Qt Qml Drawer
body: <p>I want to show only half of a QML <a href="https://doc.qt.io/qt-5/qml-qtquick-controls2-drawer.html" rel="nofollow noreferrer"><code>Drawer</code></a>. The idea is to keep some important information in the visible part of the drawer and then let the user show the full drawer with more information.</p>
  <p>From the documentation I thought that the</p>
  <p><code>position</code> property should be suitable for this:</p>
  <pre><code>Drawer {
    modal: false
    interactive: false
    position: 0.5 // does not work
  }
  </code></pre>
  <p>But setting the position does not have an effect. Is it possible to show only a part of the drawer?</p>
