body: <p>I am trying to make a combo box for an edit page. </p>
  
  <pre><code>echo $this-&gt;Form-&gt;select('status', 
                          ['empty' =&gt; 'Select Status'], 
                          ['class' =&gt; 'form-control', 'required']
                      );
  </code></pre>
  
  <p>Here I want to add 2 things : </p>
  
  <pre><code>$options = array('0' =&gt; 'Inactive',
                   '1' =&gt; 'Active',
                  );
  </code></pre>
