Enhanced Product List Add-to-Cart for PrestaShop 8 & 9 | Persistent Quantity Cart

Enhanced Product List Add-to-Cart

Persistent Quantity Controls for Category & Listing Pages (PrestaShop 8 & 9)

Executive Overview

Five years ago, Walmart.com popularized a powerful usability concept: as shoppers browsed a category, clicking Add to Cart immediately transformed into live quantity controls, allowing items to be added or removed directly from the product list.

This interaction mirrors how people shop in a physical store—walking down an aisle and placing items into a cart as they go. We implemented this same aisle-style shopping behavior for PrestaShop years ago—and took it further.

Enhanced Product List Add-to-Cart delivers a persistent, real-cart experience at the category level. Quantities remain visible and accurate even when shoppers leave a category and later return—a detail that native PrestaShop 9 does not consistently maintain.

This module has been proven in production for years and is now fully upgraded for PrestaShop 9.

What This Module Does

• Replaces the standard Add to Cart button on product listings with inline quantity controls.
• Allows shoppers to:
  • Increase or decrease quantities directly from category and listing pages.
  • Remove items without opening product pages or navigating to the cart.
  • Use a Cart icon directly from the product listing to proceed to checkout immediately.
• Persists quantities when:
  • Navigating between categories.
  • Returning to a previously viewed category.
  • Continuing a normal shopping session.
• Enhances mobile UX with tactile vibration feedback when a product is added to the cart, providing instant confirmation without interrupting browsing.
• Works seamlessly with:
  • Product attributes and combinations.
  • AJAX cart behavior.
  • Standard PrestaShop checkout flow.

This is the closest experience to a true aisle-based shopping cart available in PrestaShop.

Why It Matters

• Reduced friction: Customers manage quantities where decisions are made—no page hopping, no cart interruptions.
• Higher average order value: Inline quantity changes make multi-item and multi-quantity purchases feel natural.
• Familiar, enterprise-grade UX: A pattern shoppers already understand from major retailers and modern mobile apps.

Summary

Enhanced Product List Add-to-Cart transforms category pages from static catalogs into a responsive shopping aisle. Shoppers see what is in their cart, adjust quantities instantly, receive immediate mobile feedback, and proceed to checkout without breaking their flow—exactly where buying decisions happen.

This is not a concept feature. It is a mature, production-tested enhancement, now fully aligned with PrestaShop 9.
