Hi all, wondered if anyone can help?

I am trying to add variations to a product in woocomerce, allowing the option to purchase certain quantities ie 1, 5 or 10,

Then depending on the quantity chosen, x amount drop down boxes to choose between a list of say 20 options ie: quantity 1 so 1 box comes up with 20 different products, or quantity 10: then 10 different drop down boxes come down with the same options in each so products can be mix & matched or 10 of the same item chosen

Only price difference would be between quantities, wouldn’t vary between options within the secondary drop downs…

Hopefully this makes sense?

Thanks
