Drop-down for Yes/No?

Normally when developers present a Yes/No question on a form, they use Radio Buttons.

Would it be a “mortal sin” if I used a Drop-Down instead?

(I’m cramped on space, and looking for a way to make everything fit in the limited space I have and yet remain “usable”!)




Not all all, they’d do the same thing for a simple Yes/No options.
