				Hello gaurav1083,
Create a repeater table based on Item_type, and set its Rows and Columns property to 3 by 1(or N by 1 ) where N is the possible values for Item_type(3 in the example you showed below). Then, insert a list inside the repeater table with the data item Item_name in it. Finally, connect the Repeater table and the List with the master-detail relationship as Item_type<->Item_type.
