You have the option to determine whether a product or an option in your catalog can be visible and addable by buyers on the configurator.
By unchecking the "Selectable by acquirers" box for a product or option, you remove the ability for buyers to see that product or option on their configurator. However, the product or option will still be available in your customizations management interface.
If you have checked the "Selectable by acquirers" box for a product but its category (e.g., shower tray) is not addable by buyers due to the configuration set in the settings sheet, it will be impossible for buyers to add that product. If you want this to be possible, please contact us.
