javascript - html bootstrap dropdown menu getting reset -


i have dropdown menu in 'index.html` like

<div id="navbar" class="navbar-collapse collapse">   <form class="navbar-form navbar-right">         <div class="dropdown">           <button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">menu           <span class="caret"></span></button>           <ul class="dropdown-menu">             <li><a href="{% url 'item1' %}">item1</a></li>             <li><a href="{% url 'item2' %}">item2</a></li>           </ul>         </div>   </form> </div><!--/.navbar-collapse -->

and when click on item2 dropdown menu brifely sets item2 , menu. in item2.html calling index.html like

{% extends 'index.html' %} {% block content %} ... {% endblock %}

i think after clicking on item2 href rightly calls item2.html calls index.html when renders dropdown menu again value menu, how can keep dropdown value set selected one?
