Question

我正在尝试在剪切路径上放置下拉div而不成功。我试图使用固定位置的z-index失败。有没有办法保留剪切路径并强制将下拉内容div放置在剪切路径上？

我做了一个jsfiddle来演示下面的问题

预先感谢您的帮助！

您可以通过添加其他背景层来做到这一点。我已经修改了您的代码：

.header__top {
  position: relative;
  width: auto;
  height: 92px;
  padding: 0 32px;
}
.back-ground {
  position: absolute;
  width: 100%;
  top: 0;
  left: auto;
  bottom: auto;
  right: auto;
  height: 84px;
  padding-top: 0;
