title: Zend2: Outputting a single form element if its a radio button list?
body: <p>I have a radio button list with three options: daily, monthly, weekly. I want a way to access each one individually. For example:</p>
  
  <pre><code>echo $this-&gt;formElement($form-&gt;get('iteration')); 
  </code></pre>
  
  <p>Will print out all three values, with their labels:</p>
  
  <pre><code>[ ] daily
  [ ] monthly
  [ ] weekly
  </code></pre>
  
  <p>I want a way to iterate over all the elements. Something like this:</p>
  
  <pre><code>foreach ($this-&gt;formElements($form-&gt;get('iteration') as $element)  {
      echo $this-&gt;formElement($element); 
  }
  </code></pre>
  
  <p>But that doens't work. Any thoughts?</p>
