如何在 drop-down 菜单链接上保持悬停状态

Question

所以我有这个 drop-down 菜单，但是当我将鼠标悬停在它上面时我无法让它停留。当我将鼠标悬停在按钮上时，菜单会出现，但当我将鼠标悬停在 drop-down 菜单中的链接上时，它会消失。我试图通过更改悬停属性并包含 Li 标签来修复它，但是当我使用悬停更改代码部分时没有任何效果，菜单不再显示。我认为这与 parents 和 child 内容有关，但我不确定。提前致谢！

改为在按钮的父元素上使用 :hover：

.nav {
  position: absolute;
  left: 0;
  top: 0;
  height: 20%;
  width: 98%;
  z-index: 1;
  display: flex;

  justify-content: space-between;
}

.nav_links  {
  display: flex;
  justify-content: space-around;
  padding: 20px;
  margin-top: 250px;
  align-items: center;
  width: 45%;
  margin: left;
}

.nav_links ul li{
  padding: 12px 12px;
}

.nav_links button{
  font-size: 25px;
  font-family: Segoe UI;
  background: none;

opacity: 0;
pointer-events: none;
transform: translateY(0px);
transition: all 0.4s ease;
}

.college_btn a, .vie_btn a, .services_btn a, .portail_btn a{
