title: Rally SDK 2.00 p2 Adding several Checkboxes
body: <p>I am trying to add Checkboxes for a Rally Report version 2.00p2.</p>
  
  <p>I defined severals place holders for the filter (releaseFilter and stateFilter)
  and Adding the checkboxes at the body of the onReady function at the end. </p>
  
  <p>However, Instead of 5 different checkbox I get 1 and on top of the Release filter.
  Sorry But I couldn't add an Image.</p>

  <p>The original Entry in your javadoc is:</p>
  
  <pre><code>Ext.create('Ext.menu.Menu', {
  width: 100,
  height: 110,
  floating: false,  // usually you want this set to True (default)
  renderTo: Ext.getBody(),  // usually rendered by it's containing component
  items: [{
      xtype: 'menucheckitem',
      text: 'select all'
   },{
      xtype: 'menucheckitem',
      text: 'select specific',
   },{
      iconCls: 'add16',
      text: 'icon item'
   },{
      text: 'regular item'
   }]
  });
