Layer list widget: disable child layers when the parent layer is not selected

Hi,

I'd like to know if it's possible to disable layers (in the layer list widget) who's layer group is not selected. Such layers are not visible in the map, but are still visible and enabled in the layer list widget. I know it's trivial, but sometimes users are confused that a layer is not visible, they don't notice the group layer is not selected. Here is an example in our application:

I know that when a layer is out of range for it's defined scale, it will become disabled. This makes it clear that the layer is not visible in the map.

I'm a software developer not a GIS specialist, so I don't know if this behavior is standard or not. Still, I'm wondering if there's a way to get the same behaviour for disabled group layers as for out of range layers?

Thanks
