Catalog Items are individual content pieces that have been imported into Waffle from various web sources and organised within Catalogs. They provide a vast and diverse array of data for you to explore within the platform. In contrast, Waffle Templates are pre-designed structures that provide a starting point for creating new Toppings. They offer a blueprint with predefined layouts, properties, and organisation. Templates are valuable for streamlining the creation process and ensuring consistency across your Toppings.
