title: Show/Hide option in Select2 using toggle or similar
body: <p>I have a drop-down element which I apply <code>.select2()</code>, before, when it's a common <code>SELECT</code> element I use this code to toggle a element:</p>
  
  <pre><code>$('#orders_nat_lives_in_ccs').click(function() {
      $(".shipping_from option[value='MRW']").toggle(!this.checked);
      $(".shipping_from option:eq(" + ((this.checked) ? 1 : 0) + ")").prop('selected', true);
  
      $(".secure_shipping").toggle(this.checked);
  });
  </code></pre>
  
  <p>But this not work for Select2 what's the right way to do this using this library?</p>
  
  <p>Here you have a <a href="http://jsfiddle.net/61v9edea/1/" rel="nofollow">Fiddle</a> example around what I'm talking about, first drop-down has <code>.select2()</code> applied and code doesn't work, second one is the same but without Select2 and the same code works.</p>
