bootstrap 4 行高由特定的列设置 - 不是最高的

Question

我有一排有两个列。
第一个列包含一些必须可见的内容：它不应溢出行或滚动。
第二行包含一个我想滚动浏览的长列表，因此它不会溢出该行：

我目前正在做的是手动设置高度，并将overflow-y: scroll;设置为列表。
但我认为它可能没有我想要的那么灵敏...

.row {
  height: 175px;
  overflow-y: hidden;
}
.list {
  height: 175px;
  overflow-y: scroll;
}

任何人都有实现以下目标的解决方案：

行高相对于第一列的高度，
有第二列溢出滚动

Answer 1

您需要创建列表组 position:absolute，然后在列表和列表组上设置 overflow:auto...

.list {
    overflow: auto
}

.scroll {
    position:absolute;
    top:0;
    left:0;
    right:0;
    bottom:0;
    overflow:auto;
}
