@ChampagneCoffee setting up the composited Bundles to utilize the Item Grouping > None option should hide their title in cart/order templates. In some cases this might be a better approach than hiding the entire Bundle container line items.

Hey Manos, apologies I also wrote you an email instead of commenting here. Is it possible to revers this snippet in a way to hide the parent in the order?
