   <head>      <link rel="stylesheet" href="{{ url_for('static', filename='css/bootstrap.min.css')}}" >     <link rel="stylesheet" href="{{ url_for('static', filename='css/bootstrap-responsive.min.css')}}">     <link rel="stylesheet" href="{{ url_for('static', filename='css/font-awesome.min.css')}}">     <link rel="stylesheet" href="{{ url_for('static', filename='css/main.css')}}">     <link rel="stylesheet" href="{{ url_for('static', filename='css/sl-slide.css')}}">     <link rel="stylesheet" href="{{ url_for('static', filename='css/bootstrap-select.min.css')}}">      <script src="{{ url_for('static', filename='js/jquery-3.2.1.min.js')}}" ></script>     <script src="{{ url_for('static', filename='js/bootstrap.min.js')}}"></script>     <script src="{{ url_for('static', filename='js/bootstrap-dropdown.js')}}" ></script>     <script src="{{ url_for('static', filename='js/bootstrap-select.js')}}" ></script>       </head>     <body>     <section id="about-us" class="container main">         <div class="row-fluid">             <div class="span8" >                 <div class="blog">                    <div class="blog-item well">                     <a href="#"><h2>heading2</h2></a>                     <select class="selectpicker" id="select_county" data-live-search="true" data-style="btn-primary">                       <option>county1</option>                       <option>county2</option>                     </select>                      <select class="selectpicker" id="select_event" data-live-search="true" data-style="btn-primary">                       <option>event1</option>                       <option>event2</option>                     </select>                      <input type="submit" class="btn btn-info" value="submit button">                       </div>          </div>     </div> </div>       <script type="text/javascript">         $(document).ready(function(){         $('.selectpicker').selectpicker('refresh');        });     </script>  </body>

although data-live-search of select works, select not showing of items other selected one.
