Bootstrap Dropdown Active悬停时打开，单击时链接

我一直在尝试修改django-oscar的导航栏菜单。http://latest.oscarcommerce.com/en-gb/

我无法理解的是，"浏览商店"菜单在主页上的页面加载时仍然打开，但在所有其他页面上点击时打开。我不明白为什么会发生这种事。有没有办法让它在悬停时打开，并在单击时添加<a>标记？

这是关于oscar文档中相关部分的html模板-

<div class="navbar-collapse primary-collapse collapse">
        {% block nav_dropdown %}
            <ul id="browse" class="nav navbar-nav">
                <li class="dropdown active {% if expand_dropdown %}open{% endif %}">
                    <a href="#" class="dropdown-toggle" {% if not expand_dropdown %} data-toggle="dropdown"{% endif %}>
                        <span class="nav-line-1">Shop by</span><span class="nav-line-2">  Category</span>
                        <b class="caret"></b>
                    </a>
                    <ul class="dropdown-menu" data-navigation="dropdown-menu">
                        {% category_tree depth=2 as tree_categories %}
