Fence gate

Lately I’ve been thinking of making stables for my donkey but its looks weird how to get the donkey out he has to jump out. I thought it would be cool to make a fence gate (like in mc)that acts like a door that can open/close except its only 1 tall and donkeys can to through it while its open.it should be made with 2 wood in a wood bench

:)THAT WOULD BE JAWSOME:)

This has been suggested lots of times.
