What are Multi-level Collections?

Multi-level collections are a hierarchical system for organizing products into different levels of categories. Unlike traditional collections, which are typically flat and single-level, multi-level collections allow for deeper categorization. Each level represents a more specific category, providing users with greater granularity in their search and filtering options. This ensures a more precise and tailored shopping experience.

Here's an example with Tops as the first-level using collection followed by second-level values using tags (Bodysuits, Polos, Tanks & Camis, T-Shirts and Vest):
