Wordpress 中的子菜单下拉菜单

Question

我隐藏了我的子菜单，并添加了 css 以在将鼠标悬停在父菜单项上时显示子菜单下拉菜单。

我想做的是在“单击”父菜单按钮而不是“悬停”时让子菜单下拉。

我的 CSS 是：

.sub-menu {
    display: none;
}

.shiftnav ul li:hover > ul {

display: block; /* show sub menus when hovering over a parent */

}

        </a>

Answer 2

您可以使用li a:first-child:nth-last-child(x) { } 实现几乎相同的效果。

这是quick example。标记只是您的标准嵌套 UL，但请注意，我在 HTML 中只使用了一个类，位于根 <ul>。自己测试一下，在任何级别添加任意数量的嵌套列表！
