Co-op play in Super Mario Maker 2 is supported in two different modes.
Build Mode - In the Build Mode, two players on the same system (couch co-op) can work side-by-side to create a course on a single screen. Each player will need to use a Joy-Con controller for this.
Course World - You can play other players' custom level creations in the Course World mode. Within the "Network Play" section of Course World, there are two different co-op options: Global Play (online) and Nearby Play (local wireless LAN).
