WordPress子菜单将不可见，而是在标题中显示滚动条

Question

我希望子菜单看起来可见（像普通的子菜单一样），而不是隐藏在滚动条下，但我被卡住了

.CSS

.nav {
    float: right;
    display: inline-block;
    width: auto;
    position: relative;
}
.nav > ul > li {
    margin-right: 55px;
    overflow: visible;
}
.nav > ul > li > .sub-menu {
    position: absolute;
    padding-left: 0px;
    background-color: #fff;
    border-radius: 2px;
    border: 1px solid #ddd;
    z-index: 2;
}

.HTML：

<nav class="nav" role="navigation">
                    <ul><li id="menu-item-18" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-has-children menu-item-18"><a href="http://www.ubietest.ubieportal.co.uk/web-design/">Web Design</a>

Answer 1

您可能应该将position: relative;设置为包含下拉菜单<ul>的元素。现在，子菜单绝对是.nav元素。

另外，还有overflow: visible;为.nav > ul > li编写的规则，您可能还需要检查一下。它创建了水平滚动，我认为这是不必要的。
