Grouping Modes
At the top of the Layout Tab, use the segmented control to switch between the two core structural strategies:1. By Priority Mode
In By Priority mode, pages are sequenced strictly according to the layout importance assigned to each product.

How By Priority Works:
- Sequential Hierarchy: Pages flow from the most prominent featured items down to compact multi-product grids:
- Portada (Cover): Special front cover page.
- Índice (Table of Contents): Automated chapter index.
- 1 product page (Featured / 1st Priority): Full-page high-impact displays.
- 2 products page (Premium / 2nd Priority): Half-page balanced layouts.
- Cuadrícula de productos (Grid / 3rd Priority): Multi-product grid spreads.
- Información de Empresa (Organization Page): Special back cover contact page.
- Best Used For: Promotional campaigns, seasonal lookbooks, and sales brochures where top-tier products must capture customer attention before standard catalog items.
2. By Category Mode
In By Category mode, products are grouped into distinct thematic chapters based on their assigned product category.

How By Category Works:
- Thematic Chapters: Categories (e.g., Furniture, Electrónica, Electronics, Home Appliances) act as independent sections.
- Category Counter Badges: Displays the total count of products contained within each category (e.g.,
3 products,5 products). - Sub-tier Accordion Structure: Expanding a category reveals its internal layout tiers:
- Featured Products (1 prod / page)
- Premium Products (2 prods / page)
- Grid Products (Grid)
- Sub-tier Product Counters: Real-time badges indicate how many products in that category belong to each priority tier (e.g.,
3 prods,4 prods, or0 prods). - Best Used For: Comprehensive wholesale catalogs, retail department guides, and multi-brand catalogs where readers shop by department.
