title: Render custom Radio button in ExtJS 3
body: <p>I want to customize the radio button where I need to display text box, or Date field besides radio button instead of text. </p>
  
  <p>There is a similar question <a href="https://stackoverflow.com/questions/13611280/add-custom-item-to-radio-button-in-extjs">Add custom item to radio button in extjs</a>, but the answer is for ExtJs 4. Can someone please help me with similar implementation for ExtJs 3?</p>
  
  <p>I tried using <code>contentEl</code>, but the div gets appended below the radio input tag, so is not visible. After looking at Ext code I tried overriding private <code>getContentTarget</code> function and it seems working but doesn't feel the right approach</p>
