Well I was about to ask if anyone knew of a unit that is moveable that does not take up food (other than terran buildings) - to use as a selector.
(In my map, there is limited supply, so a unit that took up supply would be a waste).
Just to let anyone know, who doesn't...
Terran Civilians do not take up Terran (or any) Supply.
I don't know if any other units do.
(Broodlings, anyone?)
Any unit that can be created in the game without triggers don't require food.
All heros do not require food.
That sums it up.

I think he ment "that can't be created in game without triggers".
Pretty much it's any unit you can't use in normal melee and those that provide it.
No, I mean can be created. Halluncinations and Broodlings to be more specific.
I guess Seige Tank could be one that doesn't fit in here

You can also use anyunits that isn't in the player's race. Lets says hes terran, give him a zerg or prottos unit as a chooser, or use heros.
btw, it might be okay to allow the selector to take up food because it will be removed afterwards, won't it?
That really depends on what he's doing. If it's picking an initial unit at the beginning of the game, sure it will be fine. But if he gives a unit or units to the player to use throughout the game then no, that might interfere.
The Zerg Overlord hero doesn't take up food. I think we need more info on what the question might be about.
Just use a Civillian or if you want cloakage, dark templar hero
I think he got his answer already. Let's stop posting.
