Adding Multiple Variable Products To Basket

Good Afternoon,

I am desperately looking to try and add multiple Variations to the cart, at the same time. We have extended our Woocommerce with FooEvents and Some custom code to display all product variations at the same time, however we then need to be able to add multiple variations to the basket on the the single click of an add to basket button.

I.e If 2 adult tickets and 1 child ticket are selected or have quantities to buy in, then these need to be added to the basket on the click of the button?

Thank you in advance for any help received.

Kind regards,

Dave
