title: How to add option using MultiSelect jQuery plugin
body: <p>I am using the jQuery - MultiSelect plugin.</p>
  
  <p>I want to be able to add an option to my initial select box, and then have the MultiSelect user interface update with the new option.</p>
  
  <p>Here is what I have (which doesn't work).</p>
  
  <pre><code>var value = $("#newGroup").val();
  $('#Select1').append("&lt;option value=\"" + value + "\"&gt;" + value + "&lt;/option&gt;");
  </code></pre>
  
  <p>Then I've tried to call the same code to recreate the multiselect along with other options like destroying it first.</p>
  
  <p>Here is the code I use to implement the plugin.</p>
  
  <pre><code>$("#Select1").multiselect({ sortable: false, searchable: true });
  </code></pre>
  
  <p>Here is the plugin's home page:
