title: how to make a option mandatory/read-only in multiSelect dropdown checklist
body: <p>I am using <a href="http://labs.abeautifulsite.net/archived/jquery-multiSelect/demo/" rel="nofollow">jQuery MultiSelect plugin</a>. I have a requirement like -
  Make the English language selected by default and English cannot be removed by user.</p>
  
  <p>I have tried like (it is making the English always checked but value is removed) :</p>
  
  <p>JQUERY:</p>
  
  <pre><code>jQuery("#language").multiSelect({
      oneOrMoreSelected: '*',
      selectAll: false,
      noneSelected: 'Check some languages!'
  }, function(objCheckbox) {
      if (jQuery(objCheckbox).val() == "English") {
          jQuery(objCheckbox).attr("checked", "checked");
      }
  });​
  </code></pre>
  
  <p>HTML:</p>
  
  <pre><code>&lt;select id="language" name="language" multiple="multiple" style="width:300px;"&gt;
      &lt;option value="English" selected="selected"&gt;English&lt;/option&gt;
      &lt;option value="Hindi"&gt;Hindi&lt;/option&gt;
      &lt;option value="Spanish"&gt;Spainish&lt;/option&gt;
      &lt;option value="Urdu"&gt;Urdu&lt;/option&gt;
      &lt;option value="French"&gt;French&lt;/option&gt;
      &lt;option value="Bengali"&gt;Bengali&lt;/option&gt;
  &lt;/select&gt;​
  </code></pre>
