Cart pageWorks with your theme's default cart page. A custom checkout flow or a cart template from a 3rd-party app may not work correctly.
## **📝 Step 1 — Create the Cart Form in the App** 1\. Open the app > click **Forms** > click **Create new form** button 2\. The form template lists show up > select **Oder** > **Cart form**
3\. In form configuration, add elements and configure the form based on your needs 4\. Click **Save** to finish ## **📝 Step 2 — Add the Cart Form to Your Cart Page Template** > **⚠️ Special setup.** This form type and template need extra care to work. After you create the form, contact us at we'll help you add it. 1\. Form the Shopify admin page, go to **Themes** > click **Edit theme** 2\. Go to the **Cart** page template 3\. Click **Add section** > select **Form Builder app** 4\. In the **Form Builder app** element, paste the embedded code of the cart form here 5\. Click **Save** 6\. Check the online store to view the result
## **📝 Step 3 — Check form on the site** 1. Add a product to your cart and open the cart page 2. Look for the form above the **Checkout** button (or wherever you placed the block) 3. Fill it in and click **Checkout** 4. Open the order in Shopify and check **Additional details** ## 🧩 How the Cart Form Works **1 — Customer fills in the Cart Form** When shoppers are on the **cart page**, they see your cart form fields — for example: * “How did you hear about us?” * “Delivery date” * “Message” * “Agree to terms & conditions”
**2 — The form is submitted when the shopper clicks Checkout** Unlike a normal form, customers do not press a “**Submit**” button. The form is automatically submitted the moment they click the **Checkout** button. **3 — You can view the Cart Form data inside the order** When the order is placed, the cart form answers appear inside the **Additional Details** section of the Shopify order page.
