What is considered best practice for creating nested menus in Shopify?

A key component of creating nested menus in Shopify involves ensuring proper associations between top-level menu items and their corresponding sub-menus. When a top-level menu item matches the name and handle of its intended sub-menu, it establishes a clear and logical relationship that enhances user navigation and improves the overall user experience. This matching criterion allows Shopify to appropriately recognize and display sub-menu items, making them accessible to users without confusion.

The other options, while they may address aspects of menu design or functionality, do not align with the best practices specific to the structure and organization of nested menus. For example, styling top-level menu items with CSS is important for visual appeal; however, it does not influence the logical structure required for nested menus. Similarly, the placement of sub-menus and numbering menu items may be relevant for certain design choices, but they do not fundamentally impact how nested menus should be constructed in a way that optimizes navigation efficiency.
