Introduced in FiboFilters 1.11.0, the Category links – tree filter type displays product categories and their subcategories in a structured hierarchy. Unlike the Category links – flat type, which lists all categories on a single level, the hierarchical view helps users understand the full category structure at a glance. This improves navigation by allowing customers to explore deeper category levels more intuitively and quickly locate relevant products.
By visually grouping subcategories under their parent categories, this filter enhances user experience, especially in stores with extensive category trees. It provides a clear overview of available paths, making browsing more efficient and reducing the time needed to filter products.
