Question
In creative you can lock dropper, dispenser, furnace and hopper but you can't lock a chest or a trapped chest.
Why ?

I apologise for the delayed response. As far as I know it is not possible to 'lock' items in creative, but other players cannot open them unless they're added to your plot.
