How to Set Up a Form with Multiple Product Catalogs

You can use multiple Product Catalog components in a form and calculate their combined total for payment.

Steps

1. Create multiple Product Catalogs

Add a separate Product Catalog component for each category of products.

For example:

• Shirts — @shirts
• Pants — @pants

2. Add a Calculation component

Add a Calculation component to calculate the total of all product catalogs.

Use a formula such as:

@shirts + @pants

This will calculate the combined value of the selected products.

3. Add a Payment field

Add a payment field and select your preferred payment provider:

• Stripe
• PayPal
• Authorize.Net

4. Set the payment amount

In the payment field's Amount property, select the Calculation field created in the previous step.

The payment amount will then be automatically populated with the combined total of all product catalogs.

5. Publish the form

Once everything is configured, Publish your form.

Your customers can now select products from multiple catalogs, and the payment amount will automatically reflect the combined total.
