Here is a solution i've found using pure CSS: `.simplebar-wrapper:hover ~ .simplebar-track > .simplebar-scrollbar:before { opacity: 0.5 !important; }`

Yes, basicly if you set the SelectedValues programatically to some non empty collection, after the List component loading, the state of the select all checkbox should be set accordingly. ...

This issue was the main reason that i started to use [OverlayScrollbars](https://kingsora.github.io/OverlayScrollbars/) instead of the default one in my applications.
