title: CakePHP: Multiple validation rule - don't show mandatory hint in select options
body: <p>I have created a form in CakePHP where the user can select languages for a project via checkboxes. For these checkboxes, I have implemented a validation rule (more than one checkbox has to be checked). Everything works fine, but ALL checkboxes show the "mandatory" star:</p>
  
  <p><img src="https://i.stack.imgur.com/bYhDV.png" alt="enter image description here"></p>
  
  <p>This is very ugly in my opinion because it seems to the user that every checkbox MUST be checked to complete the form. My validation rules look like the following:</p>
  
  <pre><code>    'Language' =&gt; array(
          'rule' =&gt; array(
              'multiple',
                  array(
                      'min' =&gt; 1
              )
          ),
          'message' =&gt; 'Please select at least one language'
      )
  </code></pre>
  
  <p>'Language' is a seperate model and I use this for propagating my checkboxes. So, is there any trick to don't show this star near the checkboxes? The best would be to don't need to change anything on the Cake core...</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>The view code I am using for this is:</p>
  
  <pre><code>echo $this-&gt;Form-&gt;input('Project.Language', array('type' =&gt; 'select', 'multiple' =&gt; 'checkbox'));
  </code></pre>
