To keep things neat and short:
https://jsfiddle.net/m53ockLu/
.container {
max-height: 500px;
background: grey;
}
.sidebar {
height: 100vh;
width: 150px;
overflow-x: scroll;
overflow-y: auto;
background: red;
}
.element {
position: relative;
display: flex;
flex-direction: row;
flex-wrap: nowrap;
margin: 5px;
height: 200px;
width: 20px;
background: green;
}
.first {
position: relative;
display: block;
height: 20px;
width: 100px;
background: pink;
}
.second {
display: inline-block;
}
.second-absolute {
position: absolute;
height: 20px;
width: 250px;
background: purple;
}
<div class="container">
<div class="sidebar">
<div class="element">
<div class="first"></div>
<div class="second">
<div class="second-absolute"></div>
</div>
</div>
<div class="element">
</div>
<div class="element">
</div>
<div class="element">
</div>
</div>
</div>
Is it possible to keep the red container scrollable on vertical axis, and at the same time make the purple (.second-absolute) element overflow this red container horizontally? I'm totally out of ideas, I thought that overflow-x & overflow-y should do the trick, but no dice.
Thank you very much for any help.
