A well-structured "mega menu" can enhance user engagement by reducing scrolling and making website navigation more intuitive, as demonstrated by Prismic in their site redevelopment using their own product. The process involved using Prismic's Slice Machine to model both a simple top-level menu and a more complex, second-level nested submenu, employing best practices like Slices, tabs, and Slice variations. This approach allows for a balanced control over content management, providing flexibility for content teams while maintaining design consistency and quality control. The article details the technical steps taken to achieve this, including creating custom types and slice variations, and hints at future plans to simplify this process further by extending the simplicity of page types to other website elements such as navigations. Overall, the experience offers insights and inspiration for others looking to model their own nested navigations using Prismic, with ongoing developments aimed at streamlining the process.
