Trying to apply the Isotope js plugin in the category page for the products grid. Say in the Shoes category you have items with "boots" and "sandals" sub-categories and want to filter them with a little menu on top.
In order to make it work I'll need to inject css classes into the list items, next to the "first" and "last" classes.
I know changes should be applied in the content-product.php file. Adding
post_class( ); gives me everything except what I'm after... Yeah, standard WP classes but no categories, no tags, no variation values...
This will be my dream:
<li class="first shoes boots">
I'm really struggling with this and I don't know where to start
