一种解决方案是在父级（ .fieldTypes ）和 overflow-y:scroll 上设置 overflow-y:auto --- 和 —4a11dcad904bddc .fieldsContainer

这背后没有“故事”。只是您必须为父级设置默认溢出以接受它，然后在子级上指定 overflow-y:scroll( as you want vertical scroll )。

 html,body,
.wrapper{
  height: 100%;
  width: 100%;
  margin: 0;
  padding: 0;
  overflow: hidden;
}

.wrapper{
  display: grid;
  grid-template-rows: 50px 1fr 50px;
}

.header{
  border: 1px solid #ddd;
  background: lightyellow;
}

.footer{
  background: lightpink;
}

.content{
  display: grid;
  grid-template-columns: 250px 1fr 300px;
  grid-gap: 10px;
  overflow: hidden;
}

.fieldTypes{
  display: grid;
  grid-template-rows: 40px 1fr;
  overflow-y:auto;/*added*/
}

.fieldTypes .search{
  border: 1px solid red;
}

.fieldTypes .fieldsContainer{
  display: grid;
  grid-template-columns: repeat(3, minmax(70px,1fr));
  grid-auto-rows: 50px;
  grid-gap: 10px;
  overflow-y:scroll;/*added*/
}

.card{
  padding: 10px;
  background: #ddd;
