reporting services - SSRS Tables - Grouping Part Numbers without showing properties until list is dropped down -

-

i wondering if possible have ssrs table group part number , preceding field's values show after click on drop down? have list grouped part numbers , parts requirements show on same line.

how this:

|part number||requirement|value| --------------------------------    +ab1

dropped down this:

|part number||requirement|value| --------------------------------    -ab1                       r1      200                   r2      100

thanks guys!
