Product as a package

How do I offer a product at a package price, with options displaying products included within package (by default) not changing price of product. Package has a price while the option products selected have zero pricing.

If within the pkg product I currently add products under the option section, the indiv pricing of the product is displayed and cannot be changed, when product is viewed in the store the options dropdown are show with a "No" selection default and a selection for the option product with a price. Product overall final price is determined by choice selection of option dropdown plus product (pkg) price.

Or have a product where the options selected can have their indiv prices modified different from what it is if sold indiv within the shop.
