title: ExtJs panel - adding dynamic components
body: <p>I have a window with panel in inside the window. I add components to the panel dynamically. These components are in 'hbox' layout so that they are arranged horizontally. On click of a button i will add one more row of similar components in 'hbox' layout to the panel. Here the problem is that i want to add the second row below the first row, but the following code adds the components to the top of the panel.</p>
  
  <pre><code>panel.add(items);  #items is the group of comboboxes in hbox layout
  panel.doLayout();
  </code></pre>
  
  <p>Any ideas to solve this problem? so that i can add second row of components below the first row.</p>
  
  <p>Extjs Version is 3.4</p>
