If you want to apply the components of a product to another one, without having to configure them again from scratch, you can clone the components thanks to the in-built Copy components feature.
In the product settings, go to Components tab and click the button Copy components to start the cloning process.
This will open a popup window, where you can select either all the components or just some of them:
You will be able to apply the components to one or more composite products of your shop.
Please, not that you have to set up the destination products as composite products before being able to clone the component settings.
And choose whether to simply add the components to the product or to replace any existing components in the destination products.
