title: Create form by Ext.FormPanel
body: <pre><code>form= new Ext.FormPanel({ 
      renderTo: Ext.query(".foo")[0], 
      items:[]
  
  });
  </code></pre>
  
  <p>In firebug HTML-code :</p>
  
  <pre><code>&lt;div class="foo" id="ext-gen1008"&gt;
  &lt;div id="form-1014" class="x-panel x-panel-default" role="form" style="width: 1024px; height: 2px;"&gt;
  &lt;div id="form-1014-body" class="x-panel-body x-panel-body-default x-panel-body-default" style="left: 0px; top: 0px;"&gt;
  &lt;div class="x-clear" role="presentation" id="ext-gen1011"&gt;&lt;/div&gt;
  &lt;/div&gt;
  &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Where is the form tag? Or is there no form tag and is this form submit by Ajax?</p>
