Because of Child div's height, it is resizing parent div-CodePudding

My search suggestion box is not flowing all the way into the section below rather it is resizing the whole navbar. The search input is in the navigation bar. I want the search suggestions to just flow in the divs below. I have tried all the overflow property values but it is not giving me what I want.

Here's the HTML

<form  action="/" method="post">
                <div >
                    <input  autocomplete="off" name="search" placeholder="Type to Search...">
                    <div >
                        <li>Avengers</li>
                        <li>Avengers</li>
                        <li>Avengers</li>
                        <li>Avengers</li>
                    </div>
                    <button  type="submit"><i ></i></button>
                </div>
            </form>

And here's the CSS that I've tried so far

.search-box {
position: relative;
}
.nav-search {
    width: 260px;
}
.autocom-box {
    background-color: white;
    color: black;
    width: 260px;
    /* padding: 10px 8px; */
    max-height: 280px;
    overflow-y: auto;
    border-radius: 5px;
    /* opacity: 0; */
    /* pointer-events: none; */
}
.search-box li {
    list-style: none;
    padding: 8px 12px;
    cursor: default;
    border-radius: 3px;
    width: 100%;
    /* display: none; */
    overflow: auto;
}
.search-box li:hover {
    background: #efefef;
}
.search-btn {
    height: 38px;
    width: 38px;
    line-height: 38px;
    position: absolute;
    top: 0;
    right: 0;
    text-align: center;
    cursor: pointer;
    color: black;
    margin-right: 10px;
    border: none;
    background: none;
}

I've tried giving the full navbar max-height but then it tries to keep everything inside of it so it just pushes the search-box so high up it disappears. And I've also tried position: absolute; but even that doesn't work it just messes everything up.

CodePudding user response：

Adding position: absolute; to the pop-out window (.autocom-box) should just about do the trick:

.search-box {
  position: relative;
  border: 2px solid black;
}
.nav-search {
  width: 260px;
}
.autocom-box {
  position: absolute; /* This is the change */
  background-color: white;
  border: 2px solid red;
  color: black;
  width: 260px;
  /* padding: 10px 8px; */
  max-height: 280px;
  overflow-y: auto;
  border-radius: 5px;
  /* opacity: 0; */
  /* pointer-events: none; */
}
.search-box li {
  list-style: none;
  padding: 8px 12px;
  cursor: default;
  border-radius: 3px;
  width: 100%;
  /* display: none; */
  overflow: auto;
}
.search-box li:hover {
  background: #efefef;
}
.search-btn {
  height: 38px;
  width: 38px;
  line-height: 38px;
  position: absolute;
  top: 0;
  right: 0;
  text-align: center;
  cursor: pointer;
  color: black;
  margin-right: 10px;
  border: none;
  background: none;
}

(The black border is the nav bar itself, the red border is the search window)
