Finish the storefront setup
Add Product options above the buy buttons. Enable Cart option summary in App embeds, then test the cart page and cart drawer with ordinary and customised products.
The cart embed improves the storefront cart. It does not change Shopify checkout. Ride is a tested theme. For another theme, copy the theme, add the blocks, and test the copy before you publish it. Test a custom product by itself, an ordinary product by itself, and both products in the same cart. If grouped cart display is enabled, test whole-group removal and confirm that an ordinary item stays in the cart.
Orders with custom options support up to 30 cart lines, including extras, and 6 separate custom configurations. Those configurations can contain up to 40 option fields and 120 choices in total, including hidden fields and unselected choices. Several units on one line count as one configuration. Keep personalisation notes short. Very long text or complex option sets can require a smaller order. If asked, split the order. Ordinary Shopify-only orders keep their existing limits.
