When having a lot of files, the drop down will overflow beyond the page height.

I tried adding a max height / overflow-y via CSS:

.dropdown-menu{
  overflow-y: auto;
  max-height: 85vh;
}

Though that led to more weird behavior:

It looks like the overflow is leading to the child dropdowns being contained within the existing one. Weird.

I'm sure there is a way to do this with CSS, and I'm imagining it would make sense to make it into the theme. Much thanks!
