How can I do something like that in a list with two or more column? If I have in my Firebase Db something like this: Room Cabinet PaP Po 1005 A1 B 1 1005 A1 C 2 1005 A1 B 2 1005 A1 B 7 1005 A2 A 3 1005 A3 D 1 1007 A1 B 1 1007 A1 A 15 1007 A1 B 2 1007 A2 A 1 1007 A5 C 5 1009 A1 B 15 1009 A1 B 16 Room: [1005] Cabinet Room 1005 = [A1, A2, A3] PaP Cabinet A1 Room 1005 = [B, C] PaP Cabinet A2 Room 1005 = [A] PaP Cabinet A3 Room 1005 = [D] Room: [1007] Cabinet Room 1007 = [A1, A2, A5] PaP Cabinet A1 Room 1005 = [A, B] PaP Cabinet A2 Room 1005 = [A ] PaP Cabinet A5 Room 1005 = [C] Room: [1009] Cabinet Room 1009 = [A1] PaP Cabinet A1 Room 1005 = [B]
