title: How to remove scrolling inside textarea in Extjs
body: <p>I'm unable to remove scrollbar in the textarea. Data for <code>textarea</code> is coming from a json file.</p>
  
  <pre><code>{
          xtype: "fieldcontainer",
          layout: {
            type: 'vbox',
            align: 'stretch'
        },
          flex: 2,
          items: [{
          xtype: "textareafield",
          name: "Message",
          anchor: '100%',
          grow:true,
          scrollable: false,
          value: widgetConfig.NOTES,
          //width: "100%",
          readOnly: true,
          cls: "textareaStyles"
        }]
      }
  </code></pre>
  
  <p>scrollbar should be removed and the textarea height should auto increase</p>
