I have a list which gives me an output as 

Item A

Item B

Item C

For each of these Item values, there are sub items associated with them:

Item A has subitem 1, subitem 2, subitem 3, subitem4

Item B has subitem 1, subitem 2

Item C has subitem 1, subitem 2

Can we display this data in a Smart Object or a List view in K2 Five as below?

Item A  - subitem 1

                subitem 2

                subitem 3

Item B - subitem 1

               subitem 2

Item C - subitem 1

               subitem 2
