CSS FlexBox - child elements with different height?

Question

I am trying to design sub menus using FlexBox.

FlexBox default behavior is to give equal size to all child elements.

This causes all items to expand when a submenu is displayed.

Is there someway to avoid this when using Flexbox?

Codepen: https://codepen.io/dsomekh/pen/oeogGq

<style>
.single_tag{
    display:flex;
    flex-direction:column;
    margin-right:6px;
    background-color:#ADD8E6;
    margin-bottom:6px;
    padding:2px;
    border-radius: 5px;
    border:2px solid red;

}

.container{
    display:flex;

    justify-content:center;
}

.dropdown-content {
    display: none;
    flex-direction:column;

}

.dropdown-content_second {
    display: none;
    flex-direction:column;

}

.dropdown-content a:hover {background-color: #f1f1f1}

.single_tag:hover .dropdown-content {
    display: flex;
}

</style>
<html>
<div class="container">
<div class="single_tag">First div
<div class="dropdown-content">
    <a href="#">Link 1</a>
    <a href="#">Link 2</a>
    <a href="#">Link 3</a>
  </div>
</div>
<div class="single_tag">Second div
<div class="dropdown-content">
    <a href="#">Link 1</a>
    <a href="#">Link 2</a>
    <a href="#">Link 3</a>
  </div>
</div>
<div class="single_tag">Third div
<div class="dropdown-content">
    <a href="#">Link 1</a>
    <a href="#">Link 2</a>
    <a href="#">Link 3</a>
  </div>
</div>

Yes.

align-items: flex-start; on your .container will work.

.single_tag {
  display: flex;
  flex-direction: column;
  margin-right: 6px;
  background-color: #ADD8E6;
  margin-bottom: 6px;
  padding: 2px;
  border-radius: 5px;
  border: 2px solid red;
}

.container {
  display: flex;
  align-items: flex-start;
  justify-content: center;
}

.dropdown-content {
  display: none;
  flex-direction: column;
}

.dropdown-content_second {
  display: none;
  flex-direction: column;
}

.dropdown-content a:hover {
  background-color: #f1f1f1
}

.single_tag:hover .dropdown-content {
  display: flex;
}

<div class="container">
  <div class="single_tag">First div
    <div class="dropdown-content">
      <a href="#">Link 1</a>
      <a href="#">Link 2</a>
      <a href="#">Link 3</a>
    </div>
  </div>
  <div class="single_tag">Second div
    <div class="dropdown-content">
      <a href="#">Link 1</a>
      <a href="#">Link 2</a>
      <a href="#">Link 3</a>
      <a href="#">Link 1</a>
      <a href="#">Link 2</a>
      <a href="#">Link 3</a>
    </div>
  </div>
  <div class="single_tag">Third div
    <div class="dropdown-content">
      <a href="#">Link 1</a>
      <a href="#">Link 2</a>
      <a href="#">Link 3</a>
    </div>
  </div>
