Javascript 引导下拉列表活动悬停时打开，单击时链接

我一直在尝试修改django oscar的导航栏菜单

我不明白的是，“浏览商店”菜单在主页页面加载时保持打开状态，但在单击所有其他页面时打开。我不明白为什么会这样。有没有办法让它在悬停时打开并添加

{%category_tree depth=2作为树_categories%}

{%if树\类别%}

{对于树\类别，信息在树\类别%}
{%if.info.has_children%}


{%else%}

{%endif%}
{info.num_to_close%}

{%endfor%}
{%endfor%}
{%endif%}


{%block nav_extra%}
{%endblock%}

{%endblock%}

主菜单之所以这样做，是因为在
