title: Remove item from a list on second select
body: <p>I would like to remove an item from drop down list not on first time, but after selecting a second item, in the bellow example if I select option1 will remove option1, but I need to select option1 (nothing will be removed), while selecting option4 (now option1 will be removed):</p>
  
  <pre><code>&lt;select name="selectBox" class="sel" id="selectBox"&gt;
  &lt;option value="0"&gt;Select&lt;/option&gt;
  &lt;option value="option1"&gt;option1&lt;/option&gt;
  &lt;option value="option2"&gt;option2&lt;/option&gt;
  &lt;option value="option3"&gt;option3&lt;/option&gt;
  &lt;option value="option4"&gt;option4&lt;/option&gt;    
  &lt;/select&gt;
  </code></pre>
  
  <p>And this is the code:</p>
  
  <pre><code>$(".sel").change(function () {
    var getVal = $(this).val();
    $("#selectBox option[value="+getVal+"]").remove();
  });
  </code></pre>
