带箭头的CSS下拉菜单

Question

我正在尝试创建一个下拉菜单，该菜单应该有2个级别的下拉菜单。我想要一个菜单​​项（产品），当我将鼠标悬停在其子菜单（我们的品牌）上时，它应该带有一个箭头并下拉到一边。

试试这个。我从本地上传的品牌商品上的hover箭头。请检查以下代码。

/* css */

ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
  overflow: hidden;
  background-color: gray;
  font-size: 17px;
}
li {
  float: left;
}
li a,
.dropbtn {
  display: inline-block;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
}
li a:hover,
.dropdown:hover .dropbtn {
  background-color: #75c5cf;
}
li.dropdown {
  display: inline-block;
}
.dropdown-content {
  display: none;
  position: absolute;
  background-color: #f9f9f9;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
}
.dropdown-content a {
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
  text-align: left;
}
.dropdown-content a:hover {
  background-color: #f1f1f1
}
.dropdown:hover .dropdown-content {
  display: block;
}
.sub-mnu {
  position: absolute;
  left: 174px;
  top: 0px;
}
.dropdown-content ul {
  display: none;
}
.dropdown-content:hover ul {
  display: block;
}
.brnd {
