body: <p>How can I make a carousel scroll vertically on the page?</p>
  
  <p>I don't mean it's items, I mean the whole carousel.</p>
  
  <p>For example, this simple code is a carousel which won't scroll:</p>
  
  <pre><code>    var carousel = new Ext.Carousel({
          flex: 1,
          indicator: false,
          dockedItems: [Toolbar],
          layout: 'card',
          defaults: {
              scroll: 'vertical'
          },
          items: [
              {
                  html: 'Card 1'
              },
              {
                  html: 'Card 2'
              },
              {
                  html: 'Card 3'
              }
          ]
      });
  </code></pre>
  
  <p>Thanks.</p>
