Question

我正在尝试执行向左弹出的下拉菜单，但不仅第一个内联下拉列表弹出到左侧，而且顶部部分不与具有{{3的相应元素对齐}}。

下拉的其余部分重叠在一起。不仅如此，我还想要＆＃34; Moment＆＃34;的宽度。与下拉相同。

HTML代码：

Answer 1

为了使Moments项目与下拉列表的大小相同，您可能会做类似的事情：

#moments {
    width: 241px;
}

要摆脱重叠，可以为li元素添加一些余量：

ul.submenu li {
    display: inline;
    position: relative;
    margin-top: 3px;
}

Tuguldur对另一部分说了什么。

Answer 2

工作正常。但250px是静态的。

.ul li ul{
   position: absolute;
   left: 250px;
}

替换您的.ul li ul {}款式。

如何让下拉菜单正常运行？
