Category List Auto-Switching for Seamless Browsing

The patent segments the product list by organizing products into different category blocks within a single continuous list. Each category has its own anchor point, allowing the list to be divided into manageable sections without requiring full page reloads or manual category switching. This segmentation maintains browsing continuity while improving page performance by loading products in organized chunks rather than all at once.

The patent applies preliminary action by pre-establishing category anchor points and organizing product blocks according to their category affiliations before loading. This ensures that when products are loaded in a cascading manner, they are automatically placed in the correct category sections, preventing category mixing and avoiding blank areas. The anchor points are set up in advance to guide the cascading load process.

The patent implements self-service by enabling automatic category switching through detected user actions. When users scroll to the bottom of the page or pause for a predetermined time, the system automatically switches to the next category block without requiring manual clicking. This maintains clear category organization while eliminating the need for repeated user operations to navigate between categories.
