I am sorry, you are right. I am able to insert HTML code there indeed. It was a user error.
Thank you for helping me out.

Hello,

Thank you for the reply I will try to explain it in more detail.

I would like to have a catalog website with products where my customer can select items to put in the cart. When they checkout, they do not have to pay for the products. Instead, I want to receive an e-mail with the products the customer put in their cart, and make a custom quote for this specific customer, based on the products and quantity of their order.

Other way around: I would like a webshop with products, without an option of payment but still an option to add to cart and checkout.

The problem:

When I activate the ‘Just catalog’ option in the Woopress theme options, the ‘Add to cart’ button disappears when i’m on a product page. This way, customers cannot add anything to the cart…

Nevermind the plugin for now, first things first.

I hope my request is clear.

Thanks in advance.
