How to get product brands on Modx?

Question

MODX

The page displays products from the bags category. Items may have different brands. How can I display a list of brands that are presented on this page? Brands are added with the help of the Additional field (TV): brand
It's my fault, I'm a noob myself both in modex and on the web, but I've been fighting for the third day, help pliz. There are no modx specialists at work

Answer 1

How are items added? Through minishop2?
If all products have the same parent, then you can use pdoResources, for example:

Where instead of:

• 2 - specify the ID of the parent product resource (catalog)
  
• brands_tpl - specify the name of the chunk for output, or do it inline
  
• brandname - specify the TV brand name
