Why scroll-y doesn't show up? - html

Question

I want to be able to scroll vertically in the .contacts-wrapper area, but the scroll bar doesn't show up. I tried different solutions to the problem, but nothing worked out. Can someone please help me?

Answer 1

Just swap these classes in. I think this is what you want
.right-side {
position: absolute;
right: 0;
top: 10vh;
z-index: 1;
height: 90vh;
width: 20%;
background-color: #f0f2f5;
overflow: hidden; // <-- remove this if you want the full sidebar to be scrollable
}
.contacts-wrapper {
width: 100%;
height: 100%;
overflow: auto;
}
