Sidebar is not scrollable

[bakku]

Hi!
We have more models than fit to the sidebar of the interface. But the sidebar is not scrollable so we can't reach these entries of the navigation.
Any ideas how to solve this?

@bakku I added the below lines of codes and solved the problem.

#filters_sidebar_section {
  max-height: 80%;
  overflow-y: scroll;
}

But unfortunately, it still appears annoying scrollbars:

@bakku I also added overflow-x: hidden; to hide the scrollbar, but I think it is dangerous.
