I am trying to make a multiple select box after searching I found one that I wanted to build.

  <select multiple="multiple">
        <option value="1">January</option>
        <option value="12">December</option>
    </select>

    <script src="jquery.multiple.select.js"></script>
    <script>
        $('select').multipleSelect({
            isOpen: true,
            keepOpen: true
        });
  </script>
