I'm using Chrome, and I can't get these two columns to overflow with a scrollbar inside the box. Instead, they flow past the box.
I've tried messing around with heights, setting overflow: auto/scroll properties on all of the different elements at each level, nothing seems to work.
Here's a codepen of the issue:
https://codepen.io/anon/pen/vqxOBV
.sidebar-list {
overflow-y: auto;
}
I expect the columns to be contained inside the parent box, and a scrollbar to be visible for that column when the next flows past the containing box.
Edit: I'm trying to create two separate scrollbars, one for the left column and one for the right column.
