Grafana panel display based on a select dropdown value


I’m using Grafana 6.3.3 and I’m trying to look for a way to hide a panel based on a dropdown value.
Let’s say I have Windows and Linux OSType dropdown list, then I’d like to display panels related to linux only and vice versa for Windows.
I’ve tried Repeat feature with variable but it does not work for my use case.

Panel & Row repeats

Any hints ?
