I have a wrapper div and inside that div there are some buttons with a drop down, wrapper should have a max-height and an auto scroll.

The problem is if I click on a button, now the drop down always will be placed behind the wrapper, is there way to get the drop down on top of the wrapper

.bs-example
{
  display: flex;
  flex-direction: column;
    margin: 30px;
    max-height: 100px;
    border: 1px solid #F00;
    overflow: auto;
}

@Awais it's not working, do you have an updated bin? - SFernando
i added my answer - Awais
It's not showing behind the parent, it's inside the parent (the parent becomes scrollable). - Ki Jéy

There you go a working snippet here

.bs-example
{
  display: flex;
  flex-direction: column;
    margin: 30px;
    max-height: 100px;
    border: 1px solid #F00;
    overflow: auto;
}
.dropdown-menu {
    position: fixed !important;
    top: auto !important;
}

You can set left as well for align to left of div, I also use !important; to override bootstrap default styles.
