Change HTML generated in characteristics (radio button)

-- HikaShop version -- : 4.0.3

Hello guys!

I would like to ask you for a help. I am trying to stylize PRODUCT CHARACTERISTICS that are view as RADIO input on a product page.

CSS selector that I need to use looks like this:
input:checked ~ label

But unfortunately, the code of radio looks like this and there is no CSS selector that I need

<label for="xxx" .....>
<input type="radio" ... />
</label>

<input type="radio" ... />
<label for="xxx" .....></label>

Hello, Thank you very much. I will contact developer.

Best wishes,
Filip
