menu上的position: relative替换为position: fixed,并将其设置为位于底部的left: 0bottom: 0

.overflow {
  width: 100%;
  height: 100%;
  background-color: rgba(0, 0, 0, 0.2);
  position: absolute;
  inset: 0px;
  display: block;
  min-height: 2000px;
}
.menu {
  /* 👇 Add these */
  position: fixed;
  left: 0;
  bottom: 0;
  width: 100%;
  display: flex;
  flex-direction: column;
  margin-top: auto;
  background-color: white;
  border-radius: 12px 12px 0px 0px;
  max-height: 90%;
  transform: translateY(0px);
  transition: transform 250ms ease-out 0s;
}
<div class="overflow">
</div>
<div class='menu'>
  <h1>item 1 </h1>
  <h1>item 1 </h1>
</div>
