Display free in product listing for free product

-- HikaShop version -- :Business 2.2.3
-- Joomla version -- : x2.5.9
-- Browser(s) name and version -- : Chrome

Hello,
I have some free products with non-free variants.

1/In the product listing, I want to see the "free" price, but I see the cheapest variant price.

How can I show only the "free" price".

2/ Alternatively: when I select the option "all" on price display, I would like to display the price variant name in front of each price.

how can I do these two actions?

Hi,

There are no options to do that.
Both would require to modify directly the core files of HikaShop but for the second option, it would be quite difficult.
For the first option, it will require to remove the line:
$variantSearch[]=$element->product_id;
in the file administrator/components/com_hikashop/classes/currency.php
