By default, only one product can be in the cart at a time. This is because there is generally no way to remove products when using the donation forms. However, depending on the configuration and use case, it can make sense to be able to donate to several projects with a single payment.
To activate this function, please activate “Allow more than one product in cart”.
Please note the following:
This means that both donation projects and normal products can be in the shopping cart.
In the case of grouped products, the child products are removed, as otherwise the checkout process would be disrupted.
