Presently in the game, Drow are considered a wholly separate race from Elves with two sub-races, Lolth sworn and Selunites. Similarly, only Lolth sworn should have red eyes (yes, you can check allow all eye colors and make a red-eyed Selunite).
If you go back and look at all the lore of the Drow, there is no Selunite Drow. Similarly, Drow with eye colors other than red is rare (yes, Drizzt is a special snowflake for his lavender eyes).
There's no real in game reason why the Drow should be a separate race and have sub-races. It would be better to just add them under the Elf race as a sub-race there and drop the Selunite sub-race (while still allowing a Drow to choose whatever deity they follow if playing a Cleric, although first two choices for female Drow Clerics should be Lolth and Eliistraee).
Overall, it makes no sense to make Drow a separate race when they're Elves as you did not do this with Half-Elven Drow (they're listed right with the Half-Elven High and Half-Elven Wood as sub choices for Half Elves).
