Hi,
Yes, you have to configure the "product url" in the product that you use as option.
So the "i" will become a link and will use the "product url" as the url for the popup.
For the url, you do not need to create an article for each product option, you can simply use the hikashop product link.
index.php?option=com_hikashop&ctrl=product&task=show&cid=XXX (where XXX is the id of your product).
