Hello,
First, in order to be sure if you talk about Product with options like on your url link to our Demo site, it's not variant or characteristics system.
You can have look to the Product backend configuration in order to better understand and reproduce, [url=https://demo.hikashop.com/administrator/index.php?option=com_hikashop&ctrl=product&task=edit&cid[]=48]here[/url].
In order to
resume the idea :
-
Options system is to add to a
main product another product, on our website the laptop get components.
-
Characteristics/ Variants are the same main product
but with something different like color, size etc.
Hope this make your need more clear.
Regards
