Does anyone know how to use invisible bricks?

You can make invisible bricks on layer 0,5 and 6, I think, lol. On layer 6 you can make secrets, so you can make a option for this, you must only look at extras. Then you can make the Bricks are full or half or so xD maybe Brell or Freddy can better translate that...
