Creating products with customised components

[robbrazil]

Hi,

I would like to list my products, but they all have sub items or components that customise the main product and increase the price accordingly.

Example. A model train where the buyer can choose a different colorand material of paint or add extra bits to the train, etc

Or a piece of jewlery (necklace) where the buyer can add a pingent, or other item and be charged extra

Any help is very much appreciated
