How many catalog layout styles are there? How do I choose the right one?

There are seven styles in total. The company default is set in Organization & Settings → Company Profile → Appearance & Language → Catalog Appearance. Each catalog can also be changed individually on the catalog editing page: • Card (default): Suitable for traders who search by part number, like Amazon and Alibaba. • Display: Suitable for brand-focused companies, like Shopify. • Showroom: High-value items, limited products, like Apple and Dyson. • List: For comparing specs and placing bulk orders, like Global Sources. • Catalog Book: Parts and consumables, like Shimano/SRAM catalogs. • Magazine: New products and premium items. • Dense Table: Regular restocking, over a thousand part numbers. Card, Display, Showroom, and Catalog Book allow you to adjust grid size (Small, Standard, Large). List, Magazine, and Dense Table have fixed layouts. The appearance is the same on public pages, when buyers view your catalog, and when you preview it yourself. Changing the layout style does not require re-uploading items.
