Implementation checklist.

Use these checks after adapting the components to your content and application state.

  1. 01

    Keep total price and delivery impact synchronized with every choice.

  2. 02

    Explain why an option is unavailable or incompatible.

  3. 03

    Offer equivalent substitutions without silently changing the order.

  4. 04

    Preserve configured choices when a payment or network step fails.
