Add-to-cart elements let supporters build a cart-like giving or purchase experience before checkout.
Use Add to Cart when supporters may select multiple sponsorships, funds, or form-connected items before completing payment.
Add to Cart is created from Create > Element and is installed on your website. It is a website element, not a Fundraiser Form amount button type, so it works best on pages where the supporter is choosing from multiple visible options before checkout.
Use Add to Cart for sponsorships or campaigns where supporters may add more than one item before completing payment. Hosted pages do not use Add to Cart; use it on pages where the CharityStack embed script is installed.
Allowed and disallowed domains control where the cart can appear. Add your organization's website domains, not CharityStack-hosted page URLs. After publishing, test the full cart flow so you can confirm item names, quantities, funds, and totals are clear.
