title: How to seperate radiobuttons from radiobuttonlist and set it default
body: <p>I'm new to Yii framework. I'm using two radiobuttonlist in my advanced search form. I'm using the below lines to create radiobuttonlist. </p>
  
  <pre><code>&lt;div class="row"&gt;
          &lt;?php #echo $form-&gt;label($model,'ReviewedDate'); ?&gt;     
                  &lt;?php echo $form-&gt;radioButtonList($model, 'ReviewedDate', 
          array('1' =&gt; 'Reviewed', '' =&gt; 'Not Reviewed')
      ); ?&gt;
      &lt;/div&gt;
  
         &lt;div class="row"&gt; 
                  &lt;?php echo $form-&gt;radioButtonList($model, 'Approved', 
          array('0' =&gt; 'Rejected', '1' =&gt; 'Approved')
      ); ?&gt; 
      &lt;/div&gt; 
  </code></pre>
  
  <p>Now, I want to create a seperate radiobutton(4 buttons - Approved, Rejected, Reviewed, Not Reviewed) from the radiobuttonlist and <code>Not reviewed</code> has to be the selected by default when I go to that page.At a time only one button can be selected. How can I do this</p>
