I'm creating a shield for arduino and to avoid recreating it in future, I created its base as component(both schematics and pcb) and only added arduino header pads in it. Everything is just working fine except in PCB designer when I put any other component inside the shield component, then both components gets green(error). Which is very correct behavior though. But I want other components to be inside as its a shield.
I even set shield component height to 15mm. But still error is not going away.
Edit (inserted 3D screenshot) :
How can I make shield component allow to have other component inside ?
