我有一个非常长的移动菜单,有4个菜单项,每个项目都有下拉菜单,第一个下拉菜单很长,当我在第一个下拉列表中滚动浏览导航时,我无法进入最后一个下拉列表在我的菜单中,除非我关闭第一个下拉列表,但我希望能够进入最后一个下拉列表,即使第一个下拉列表打开.
这是HTML
.navbar-collapse {
height: 100vh;
}

我尝试过以下方法：
.navbar-collapse {
height: 100vh;
}
但是当第一个打开时,我仍然无法进入最后一个下拉菜单.
解决方法
Bootstrap将绝对定位放在他们的.dropdown-menu类上.只需相对定位它就应该是金色的.请参阅代码段中的修改.
.dropdown-menu{
position:relative;
}
