So I have a complex product. It is a composite product with a number of bundles products within it as well as variable, virtual products. I have been searching all day for a way to hide the variable virtual components and just have the main item "Gift Hamper" and the bundled item visible i.e. chocolate flavour rather than the box size and the 'choose 6 chocolates' component which have magically vanished. No idea how you know what to scrap, but you did it! Thank you :)

@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?
