Cool. (That's not a "FSA," though.)
Adoption assistance programs are tax-qualified under Code Section 137, not Code Section 125 (the section governing cafeteria plans), and when funded soley by the employer they don't need to be part of a cafeteria plan. This is because, without employee contributions, the adoption assistance program won't be on the cafeteria menu as one of the options for how to spend his/her compensation.
If there are no employee salary reduction contributions toward the adoption assistance program, go back to the non-ERISA benefits question and uncheck "Adoption assistance account (adoption assistance FSA)."
