question on installing drop ceiling fluorescent lighting

I bought those 2*4 panel drop ceiling flourescent lights. The ones i purchased didnt include the metal "whip" . can i just take a 4-5 ft piece of romex and run it into an electrical box? Does this meet code?

NEC 336-18 Exception #3. This seems to permit not more than 4 1/2 feet [unsupported] for a connection to "lighting fixtures or equipment." [99 code]
This seems to allow it. My own experience has been always to use whips of flex or MC cable.
How do intend to support these fixtures?

the fixtures are supported via the main tee on the drop ceiling. I hope this is the information you were seeking

I ask because the Code also requires these drop in lights [troffers] to be screwed or attached to the grid with clamps to the grid.
Furthermore, some or many local jurisdictions require that the fixtures be supported [loosely] by two ceiling grid wires at diagonally opposite corners. These grid wires cannot be the same as those supporting the grid. Interrogate your local building inspector about this.
