I need to add a post filter on the blog depending on neighborhoods and prices, it talks about restaurants, and I created some categories (Estrella Michelin, Cocina de Autor, Local de moda, Azoteas y Terrazas, Internacional, Asiático, Carnes, Pinchos y Tapas, Italiano, Gastronómico, Indio, Mediterráneo, Grandes Chefs) and I don’t know if those topics are also two categories to add on the posts or tags. I need to know how can I do this.
