title: Zend framework disable radio button in multioption element
body: <p>Hi I am trying to disable one radio button value at multioption element</p>
  
  <pre><code> $elements[] = $em = $this-&gt;createElement("radio", "tshirt-$member",array(
          "separator"     =&gt; " ",
          "belongsTo"     =&gt; "tshirt",
          "class"         =&gt; "flow",
          "parentClass"   =&gt; 'renew-donation-holder',
          "label_class"   =&gt; 'span6',
          "multioptions"  =&gt; $options['options'],
          'value'         =&gt; ct_get($this-&gt;memSession, "tshirt.tshirt$member", $entry-&gt;athlete-&gt;tshirt_size),
  
        ));
  </code></pre>
  
  <p>try to disable it with radio button value</p>
  
  <pre><code>$em-&gt;setAttrib('disable', array( 'L'));
  </code></pre>
  
  <p>or to add </p>
  
  <pre><code>"disable" =&gt; array("L")
  </code></pre>
  
  <p>Is there any solution for this, another option is to add data atribute as some kind of flag?</p>
