Expected:
Row 1: dropdown list 1 has valueMap like: { "1" : "Dog", "2": "Cat" } when i selected "Dog" => dropdown list 2 have valueMap like: { "1": "Alaska", "2": "corgi" }
Row 2: dropdown list 1 has valueMap like: { "1" : "Dog", "2": "Cat" } when i selected "Cat" => dropdown list 2 have valueMap like: { "1": "Munchkin", "2": "Ragdoll" }
