I have various components that I want regroup in the same category. I found numerous screenshots on the internet using some sort of frame surrounding items. For instance : http://www.vieartificielle.com/images_robot/e70d6615e7b9c9ecfacdc7e977425d6d/cache_500_wifi_robot_photo_gui.jpg (the frame surrounding "Joystick information" section) and http://bp3.blogger.com/_45gEBj4xUTA/RwefQvOgIjI/AAAAAAAAACQ/pKezYz2qQCQ/s320/RobotUI.jpg (the frame surrounding "Current data" section). I dont know how to get the same thing. Hope you can help !
