Customization of configurable options during checkout

I have set up 3 configurable options on my main product.

For example, each of the feature, I use "Yes/No" option to activate or deactivate so i could get 7 combinations, such as

{

1,

2,

3,

1,2

1,3

2,3

1,2,3

}

Here come my expectation: In the order form, the customer is required to choose minimum 1 configuration options, in order to proceed with order checkout.

How to validate this condition while using custom hook?

for something like this, where it's so specific to your situation, you might be better off posting in Service Offers & Requests and paying a developer to write a custom solution for you.

it would take a developer less time to actually code the solution, than it would for me to explain the generalities behind the solution, let alone the specifics for your situation.
