Display attributes in category view

Hi,

I'm trying to display the product attributes in the category view on my website. At the moment the attributes show when I go in to each individual product, but the category view only has the product name and price showing. I've searched and couldn't find a way to get the product attributes to show in the category view.
Can anyone help?

It might give you an idea

I just turned this into an ocmod for opencart 3. I have 2 versions, one that will display all attribute groups in grid/list view, and another that allows you individually select which attribute groups are displayed. Check out the demos at bensopencartdemostores.com
