title: How to dynamically hide and show tabs in tabpanel
body: <p>I have tabpanel and 2 items inside. I need dynamically hide or show tabs and select only one of items if hide.</p>
  
  <p>Code example</p>
  
  <pre><code>{
       xtype    : 'tabpanel',
       items: [
             {
                  xtype: 'container',
                  title : 'Group Info'
             },
             {
                  xtype: 'container',
                  title : 'Product Info'
             },
           ]
      }
  </code></pre>
  
  <p>So in some cases I have to hide tabs and show only product info container...</p>
