Using Offset To Display Data From A Table?

I have a dropdown list for data validation on the "display" tab. The dropdowns come from a named range on the "Parts List" tab. When you select a part from the data validation list on the "display" tab it displays the data along the same row from the "data" tab. What i am trying to do is create the logic that will allow it to also display the information below until it hits a new part.

For Example:

If I choose "part1" in cell A1 dropdown list on the "display" tab, it will display "a,1,2,3,4" from cells A3 to E3 (this data comes from "data" tab cells B1 to F1). I also want to include the information in the rows below until it hits a new part. The number of rows may vary. Something along the lines of IF(A1) show B1 to F1, then if A2=blank then show B2 to F2, then if A3=blank display B3 to F3, etc. I need this to be dynamic, if the cell below is blank then display row info.
