title: How to add div class in custom addField form function in magento?
body: <p>I have created a custom module with some fields. I have used Varien_Data_Form for creating form with fields. I have added radios buttons, I just want to add one <code>&lt;div&gt;</code> between those radio buttons. I don't know to do that.</p>
  
  <p>My radio button code for form:</p>
  
  <pre><code>   $productField=$fieldset-&gt;addField('radio2', 'radios', array(
        'name'      =&gt; 'house_building',
        'value'  =&gt; '1',
        'class'  =&gt; 'house_building',
        'values' =&gt; array(
                          array('value'=&gt;'1','label'=&gt;'House','id'=&gt;'house'),
                          array('value'=&gt;'2','label'=&gt;'Building','id'=&gt;'house'),
                     ),
      ));
  </code></pre>
  
  <p>I have printed this form in view page using:</p>
  
  <pre><code>&lt;?php echo $this-&gt;getChildHtml("suggestions_edit_form") ?&gt;      
  </code></pre>
  
  <p>I got 2 radio button in the following format:</p>
  
  <pre><code>    &lt;div class="value"&gt;
     &lt;input name="house_building" class="house_building" value="1" id="radio21" checked="checked" type="radio"&gt;&lt;label class="inline" for="radio21"&gt;House&lt;/label&gt;
    &lt;input name="house_building" class="house_building" value="2" id="radio22" type="radio"&gt;&lt;label class="inline" for="radio22"&gt;Building&lt;/label&gt;     
        &lt;/div&gt;    
  </code></pre>
  
  <p>Now I want to change this is in the following format with extra <code>div</code> tags:</p>
  
  <pre><code>    &lt;div class="value"&gt;
      &lt;div class="field-container col-xs-12 col-sm-12 col-md-12 col-lg-12"&gt;
      &lt;input type="radio" checked="checked" id="radio21" value="1" class="house_building validation-passed" name="house_building"&gt;
      &lt;label for="radio21" class="inline"&gt;House&lt;/label&gt;
      &lt;/div&gt;
      &lt;div class="field-container col-xs-12 col-sm-12 col-md-12 col-lg-12"&gt;
      &lt;input type="radio" id="radio22" value="2" class="house_building validation-passed" name="house_building"&gt;
      &lt;label for="radio22" class="inline"&gt;Building&lt;/label&gt;          
      &lt;/div&gt;
      &lt;/div&gt;
  </code></pre>
  
  <p>I don't know how to do this?</p>
  
  <p>Can anyone help me to fix this?</p>
