Add input field to a product option

-- HikaShop version -- : 3.2.2
-- Joomla version -- : 3.83
-- PHP version -- : 7

Hi,

I am trying to use Hikashop to build a web hosting catalog and cart workflow. In doing so, I would like to add a custom input (text) field in the hosting plans options (which are theselved products (domains) I created) for which I would like the user to specify a domain name into.

Example:

PRODUCT:
Web hosting plan ABC @10$

OPTIONS (products):
.com domain [ ] @ 5$
.ca domain [ ] @ 8$
.net domain [ ] @ 8$

I've managed to use the Custom field "Item" as a solution. This only renders on the full product view though. Not when the product is used as an option in the main product ? I've attached a screenshot to explain.

So, the question becomes, how can we display/render custom fields in product options ?

Thanks for any help!
Danny

I did that but like the screenshot shows, the field doesn't appear in the product options (frontend) ?
I still will want to figure this out but for the record, I just assigned a mandate to a developper for a custom product template as this got a whole lot more complex since this AM
Thanks
Danny

Ahhhhh !!!
Yes, i see your point
Thanks, that's a great lead to where I wan't to bring this
