The Mix & Match tab on a simple product: enable the bundle, set pick quantity, pricing mode, and component source.
HDWebmobile Mix & Match Bundles turns any WooCommerce simple product into a “build a box” bundle picker. Instead of a plain Add to Cart button, shoppers see a grid of eligible components and choose exactly the number of items you configure before they can add the bundle to their cart.
Edit a simple product, open its Mix & Match tab in the Product data box (Screenshot 1), and tick Enable Mix & Match.
Pick quantity is the exact number of components a customer must choose before they can add the bundle to their cart — there’s no min/max range, it’s always exactly this number.
Component source is either:
* Product category — any published, purchasable product in the category you pick is automatically eligible (add new products to that category later and they’re automatically includable, no bundle edit needed).
* Manual product list — hand-pick the exact eligible products yourself.
On the product page, eligible components appear as a grid of cards, each with a −/+ stepper (Screenshot 2). A running Selected: X / Y counter and the bundle’s live total update as they click, and Add to cart only enables once they’ve picked exactly the required quantity.
Once added, the exact picked breakdown (e.g. “2 x Beanie, 2 x Hoodie, 1 x T-Shirt”) is attached to that cart line item and follows it everywhere — the Cart page (Screenshot 3), Checkout (including the WooCommerce Checkout block, not just the classic shortcode checkout), the resulting order in WooCommerce > Orders, and the customer’s order confirmation/order-details emails. You never have to guess what a customer picked after the fact.
