title: ZF2 Form\Element\MultiCheckbox: how to get each item on a new line?
body: <p>I've been Googling this to no avail. I have a multi-checkbox form element in one of my forms. Here's the code I used to create it:</p>
  
  <pre><code>$this-&gt;add(array (
      'name' =&gt; 'thingyId',
      'type' =&gt; 'MultiCheckbox',
      'options' =&gt; array (
          'value_options' =&gt; $thingyArray,
      )
  ));
  </code></pre>
  
  <p>In my view script, I have this:</p>
  
  <pre><code>&lt;?= $this-&gt;formRow($form-&gt;get('thingyId')); ?&gt;
  </code></pre>
  
  <p>The form element shows up fine, but all of the checkboxes are on a single line. How do I get it so that each checkbox is on a new line?</p>
