Question

这是我的 html 代码

<ul class="list">
    <li class="pagenav">
    <a title="Government" href="#">Government</a>
        <ul>
            <li class="page_item page-item-14"><a href="#">Code of Ordinances</a></li>
            <li class="page_item page-item-5267"><a href="#">Finance</a>
                <ul class="children">
                    <li class="page_item page-item-16"><a href="#">Fiscal Year</a></li>
                    <li class="page_item page-item-5280"><a href="#">Comprehensive</a></li>
                </ul>
            </li>
            <li class="page_item page-item-5267"><a href="#">Finance year</a>
                <ul class="children">
                    <li class="page_item page-item-16"><a href="#">Year</a></li>
                    <li class="page_item page-item-5280"><a href="#">Comprehensive year</a></li>
                </ul>
            </li>
        </ul>
    </li>
</ul>

默认显示这样

Government

Code of Ordinances

Finance

Finance year

然后点击像这样的金融节目

Government

Code of Ordinances

Finance

Fiscal Year

Comprehensive

Finance year

我的意思是说我想默认隐藏财务和财务年度的子菜单，然后单击财务和财务年度该时间子菜单显示和隐藏
