Add the components
Insert the buy components from the Insert tab, they share a single cart.
Updated:
You add the three buy components directly from the plugin's Insert tab, by click or drag-and-drop. On insert, the Wix Client ID and matching theme colors are pre-filled automatically.
BuyButton, VariantSelector and FramixCart share the same cart as long as they use the same Wix Client ID. A product added via the BuyButton therefore also appears in the FramixCart.
Checkout always redirects to the Wix hosted checkout. For this to work, your Framer domain must be listed in the allowed domains of your Wix headless app.
