网格CSS导航栏样式问题

问题描述 投票：0回答：1

我想让我的导航栏下拉列表使用CSS Grid在3列中的“关于”下显示内容（如下图所示）。我希望“nav-first-col”中的内容位于第一列，“nav-second-col”中的内容位于第二列，“nav-third-col”中的内容位于第三列柱。但是，无论我尝试什么，“关于”下的内容似乎只显示在1列中。

Picture of What I Want

.nav-bar-main-menu .dropdown:nth-child(2) ul li{
  display: grid;
  grid-template-columns: 150px 150px 150px;
  grid-auto-rows: auto;
  grid-gap: 1em;
}

.nav-first-col{
  grid-column: 1 ;
}

.nav-second-col{
  grid-column: 2 ;
}

.nav-third-col{
  grid-column: 3 ;
}

不是很熟悉网格系统，但这似乎有用吗？
