I am not an expert on themes but i would like to know if it is possible to accomplish that:
Once i pull a panel into a facet i am hiding the panel by disabling the output tag and setting a special css class only for the designer client.
Has somebody tried to do that automatically in themes by checking if the panel is in a facet(Maybe ask for the key: property)?
I have tried to change the panel but i dont know how to set a certain style class based on a property of the panel.
