From Transylvania County Schools:
On the online menus site, when clicking on the dropdown for allergens, it has all allergens checked and parents need to uncheck the allergens their child might have. From a user standpoint, it would make more sense to have it uncheck all the allergies and show all menu items - when they check an allergy (i.e. "My child has a dairy allergy") it would then cross off the items that have that specific allergen.
