Product features and options aren´t added

-- Joomla version -- : 2.5.0
-- PHP version -- : 5.6.0

I have a problem creating a product. I create a bathroom faucet and that faucet has 3 different options each with a different price. Also I want to add supplements to the tap in case the customer wants to add. Logically this supplement is added to the price. The problem is to choose the option that complement but do not add to the price.

Hi,

The options won't be taken into account with the characteristics displayed as a list. The way the system is done, it's not possible. Change the "characteristics display method" setting of the HikaShop configuration to something else and it will work.

Could you tell me the route, please?

You can find the setting "characteristics display method" in the Product section of the Main tab of the HikaShop configuration:
take.ms/xzNJ7

You may have a product value and add 3 characteristics with different values ​​?

Yes, you can have several characteristics with several values for the same product.
