Storefront Display & Cart
Custom options configured by marketplace vendors automatically render on storefront product pages and seamlessly integrate with shopping cart calculations and checkout summaries.
Product Page Option Display
When a customer views a product on the storefront, all custom options created by the seller are displayed under the product purchasing block:

Dynamic Price Calculation
When customers select or type values into custom option fields:
- Frontend JavaScript dynamically calculates option price adjustments (fixed dollar amounts or percentage additions).
- The final product price updates in real-time on the storefront view without requiring a page refresh.

Shopping Cart & Checkout Summary
When a shopper adds the product to their shopping cart:
- All selected custom options and entered values are saved with the cart item.
- The shopping cart summary displays a clear breakdown of each option choice and price adjustment.
- The selected options are preserved through checkout, customer order invoices, and seller order details.
