title: jQuery multiselect stays on height 39?
body: <p>I am busy with the multiselect from jQuery UI: <a href="http://www.quasipartikel.at/multiselect/" rel="nofollow noreferrer">http://www.quasipartikel.at/multiselect/</a></p>
  
  <p>But the select box is not growing bigger and stays on the height 39px and won't go bigger?!</p>

  <p>JS:</p>
  
  <pre><code>$("select.multiple").multiselect({});
  </code></pre>
  
  <p>How can i fix this? I get now errors that something is going wrong...</p>
