Tick Meal Prep Categories, Meal Catering Categories, or Product Categories in Pages to show on header. The first two both need the Meal Categories module, and Product Categories needs the Products module. Each creates a dropdown, titled with its Name: ... row (Categories / Product Categories by default), listing your categories and linking to the A la Carte page, catering menu, or Products page pre-filtered by that category. A dropdown is only shown when at least one category exists.
