I'm trying to set up a 'box' order item which costs £100. When a user chooses the box, they have to pick 16 items to complete the box order. So something along these lines with 16 options/radio buttons a user has to select before the box is added to your cart.
Is this possible to do with Shopify?

Yes, this is definitely possible and it's all thanks to our apps that help with allowing our merchants customise more than what's available built into our admin.
This Product Bundle app is perfect for merchant who not only want to sell "kits" or "boxes" that include individual items that may be involved in separate kits. It's also useful for merchants who want to offer discount bundles.
I would definitely recommend having a look at the app above in order to help you set up a "box" order item like what you had described in your post.
I hope that helps! :)
