title: Getting all options in a multiselect
body: <p>I am using bootstrap-multiselect and I want to get all the options (not just selected ones) for a given multiselect. I know I can get the selected ones using the following code:</p>
  
  <pre><code>var options = $('#myMultiselect option:selected');
  </code></pre>
  
  <p>But I am not sure how to get ALL the options and not just selected ones. </p>
  
  <p>Effectively, I want to dynamically modify the list of options based on some event and thus want to get hold of the list so that I can modify it. </p>
