Choose variant on category page

Hello,

I read this thread www.hikashop.com/forum/product-category-...ct-listing-page.html
but it was 3 years ago, maybe there are new options?

On the URL I sent, you can see table view with many products. It works great, but now the client want to add an extra option for every product, a certificate which increases the price +70. For the first product in this given category I addes options to choose, but is there a way to choose them on category page? I don't want to have a single product view nowhere on this site.

Please help!
