reduction or paid option

hello,

I try to add options (positives or negative) to some products
there should be a dropdown or a check box, and if chosen ther will be a major or minor price
let say a product with warranty or not.
or trousers always sell with a belt ( and if the customer does not want the belt it is -10€
I do not want an option product, because it is not a product
how could I do ?

Hi,

You can do it as an option product.
And if you don't want the option product to be displayed as a stand alone product, just assign it to an unpublished category so that it won't appear on products listings on your frontend.

thks,
but it appears in cart as a product ( with + and - and value)
I'd like to have an option as radio button
for instance sugar / no sugar and if no sugar it is cheaper
but do not want to order more sugar end so on

I guees it would be a good feature to have that (others shop as vm does that) (I am doing comparaisons)

Hi,

That's because you have the "group options with product" setting turned off in the HikaShop configuration.
Turn it on and you'll see that the option product will appear as an option of the product in the cart and not as a separate product.
