Layer Switcher - Layer does not need the group to be marked to be visible

[NicolasSvaiger]

I want the layer to be visible even with the group unmarked, so that when the group is marked, turn on all the layers present in it and if it is unmarked, turn them off.
Group turn on

Group turn off

Group off, layer on

You have to do it programmatically.

Thanks, worked. But the layers and layers group are inverted.

[NicolasSvaiger]

The GroupLayers they are being added inverted, when I place, for example, the groups on the map: Base, Over, Extra.
He is:
Extra
Over
Base
Rather than:
Base
Over
Extra

[Viglino]

That’s the standard behavior: extra is on top of the other layers and base is the lower one. The order reflect what is seen on the map.
