How to configure a "Set product"?


im trying to create a product where my customer can chose the qty of included products.

e.g. We have a birthdayparty site. where we sell party accessoires.

And we want sell a set where the customer can choose the qty of the product for each product.

A set includes the products:





Now the customer choose the qty for each product e.g 4x cup, 4x plate, 5 Birthdaycards, 20 napkins.

i tried to realise this with options

Option Cup, value 1,2,3,4,5,6,7,8,910

Option plate, value 1,2,3,4,5,6,7,8,910

Option birthdaycard, value 1,2,3,4,5,6,7,8,910

Option napkins, value 10,20,30,40

this will work, but the inventory control will not working, cause the inventory in options is only available with combinations.

The perfect solution would be the product configurator addon, but i cant qty for the child products.

The buy together addon didnt work also, because the qty i always the same for all products.

Has anyone an idea/addon for me?
