Hi Radomir,
1. Brands – I’ve checked the “Perfect WooCommerce Brands” plugin and what you need is:
[alg_product_terms taxonomy="pwb-brand"]
2. Product attributes – if, for example, you have a product attribute with size slug, then what you need is:
[alg_product_list_attribute name="size"]
Hope that helps. Please let me know if something is not working as expected or if you have any questions. And if you like the plugin, please consider leaving us a rating.
