WCIF/Modding Request real bookshelf as door

I decided to build an awesome vampire mansion with many secret rooms just known by the vampire living there, so I decided I use those bookshelf doors that I never used or even unlocked because for some reason I never played with an writer or an secret agent....anyways I think anyone with an IQ as high as room temperature would think that something isn't quite right if one of the bookshelfs is flat compared to the others.

So what I'm looking for is an secret door that actually looks like an real bookshelf and maybe even works like one
