Hi AndyWongHK, for the Dungeon version, Minecraft Dungeons has local co-op, though it's not technically split screen. The screen never splits, but it will zoom out a bit to keep characters on screen. Note that you need at least two controllers to play multiplayer on PC (keyboard/mouse and one controller won't work). Players can spread out some as the camera zooms out, but wander too far away and you'll be warped back to the side of the party leader.
There is still an on-going feedback thread for the split screen to be integrated to the PC versions of the game and the link will be below and hopefully Mojang will enable this anytime soon.
