Boostrap Select

It doesn’t show output <option>. It shows only the select with no element inside. I’m using bootstrap-select library. What’s the problem?

  $(function () {
    $('select').selectpicker();
  });

<select class="selectpicker">

</select>

Answer

You don’t have any problem: It’s working here:

Try to set the function like this (inside script tag):

  <script type="text/javascript">
    $(function () {
      $('select').selectpicker();
    });
  </script>
