html - 如何让div停止移动其他div而不改变css中的位置？

Question

我有一个下拉菜单，其中包含不同的框，当它打开时它们会一个接一个地显示，这使得其他 div 根据显示的框数向下移动。我尝试过使用position:absolute;，但这只会弄乱盒子，即使我想要一个接一个，它们也会全部堆叠起来。

@import url('https://fonts.googleapis.com/css2?

600;
700&display=swap');
 ::selection {
  color: #fff;
  background: #664AFF;
}

.wrapper {
  max-width: 450px;
  margin: 70px auto;
}

.wrapper .search-input {
  background: #fff;
  width: 100%;
  border-radius: 5px;
  position: relative;
  box-shadow: 0px 0px 5px 3px rgba(0, 0, 0, 0.12);
}

.search-input input {
  height: 55px;
  width: 82%;
  outline: none;
  border: none;
  border-radius: 5px;
  padding: 0 60px 0 20px;
  font-size: 18px;
  box-shadow: 0px 1px 5px rgba(0, 0, 0, 0.1);
}

.search-input.active input {
  position: absolute;
  border-radius: 5px 5px 0 0;
}

.search-input .autocom-box {
  padding: 0;
  opacity: 0;
  pointer-events: none;
  max-height: 280px;
  overflow-y: auto;
}

.search-input.active .autocom-box {
  padding: 10px 8px;
  opacity: 1;
  pointer-events: auto;
}

.autocom-box li {
  z-index: 99999;
  list-style: none;
  padding: 8px 12px;
  display: none;
  width: 100%;
  cursor: default;
  border-radius: 3px;
}

.search-input.active .autocom-box li {
  display: block;
}

.autocom-box li:hover {
  background: #efefef;
}

.search-input .icon {
  position: absolute;
  right: 0px;
  top: 0px;
  height: 55px;
  width: 55px;
  text-align: center;
  line-height: 55px;
  font-size: 20px;
  color: grey;
  cursor: pointer;
}

<!-- Search Bar -->
<div class="wrapper">
  <div class="search-input">
    <a href="" target="_blank" hidden></a>
    <input type="text" placeholder="Search for other alternatives ...">
    <div class="autocom-box">
    </div>
    <div class="icon"><i class="fas fa-search"></i></div>
  </div>
