Hi,

I've added the 'Folder View' widget to my Panel, but it doesn't open subfolders on hover. How can I make the subfolders cascade open with the mouse?

I'm using OpenSUSE Leap 42

Looks like that feature wasn't implemented for folder views in the panel (I see the same behavior in KDE 4.14 - regardless of the settings it won't show additional popups for subfolders).

Because of this I've always used the QuickAccess plasmoid for browsing in the panel.
