Shopify **Combined Listings** (a Shopify Plus feature) groups several products onto one product page, where each child product keeps its own inventory, variants, and URL. Without special handling, STOQ would only see the first product loaded and wouldn't update the button when a customer switches child products. STOQ's Combined Listings integration fixes that. ## Before you begin - **Shopify Plus** plan (Combined Listings is Plus-only). - An **Online Store 2.0** theme. - Combined Listings already configured in Shopify, with each child product added to your preorder offer where relevant. ## Turn it on 1. **Open your Integrations** Go to **Preorders** > **Settings**, or **Back in stock alerts** > **Integrations**, and scroll to the **Integrations** area.

The STOQ team enables the integration for your store. It's a one-time setup and works automatically afterward. [Image: The STOQ app Integrations area with the Combined Listings panel expanded, headed 'Combined Listings' and explaining it is a Shopify Plus feature grouping multiple products onto one page, that the integration needs to be configured by the support team, and that once enabled STOQ auto-detects the selected child product and shows or hides the Preorder and 'Notify me when available' buttons, with a 'Contact support' button at the bottom; with markers: 1 on the Contact support button.](https://help.stoqapp.com/images/general/stoq-with-combined-listings-3.png) ## What happens after setup When a customer switches between child products, STOQ detects the change, fetches that product's inventory and preorder status, and shows or hides the button accordingly. For example, if the Red shirt is on preorder but Blue is in stock, the Preorder button shows for Red and the Notify me logic applies to Blue. It works for both preorders and back in stock alerts. Child products with more than 250 variants have their extra variant data fetched in the background. ## Troubleshooting ### The button doesn't change when I switch child products The integration isn't enabled yet. Open the **Combined Listings** card and contact support to set it up. ### The button only works for the first product Some child products aren't in the preorder offer. Each child is a separate Shopify product, so add them all to the offer. ### No button at all Check the app embed is on. See [Enable STOQ on your theme](https://help.stoqapp.com/general/enable-stoq-on-your-theme/). ### The wrong product shows after switching That's usually a stale browser cache. Clear it or try an incognito window. ## FAQ ### Do I need theme code changes? No. Once support enables it, it works automatically with no code changes on Online Store 2.0 themes. ### Can I enable it myself? No. It needs backend configuration by the STOQ support team, which is why the card routes you to contact support. ### Does it cost extra? No. It's included with your STOQ plan. ## Related guides - [Set up preorders](https://help.stoqapp.com/preorders/set-up-preorders/): Create the offer and add each child product. - [Preorders by product variant](https://help.stoqapp.com/preorders/preorder-inventory-settings/): How STOQ reads inventory per variant. - [Enable STOQ on your theme](https://help.stoqapp.com/general/enable-stoq-on-your-theme/): Confirm the app embed is on.
