WP plugins for Product web catalog [closed]

In your position, I’d use custom post types and taxonomies. I could recommend the following:

• Custom Metadata Manager
• Ultimate Post Type Manager
• Ultimate Taxonomy Manager

With these you can implement a post-like group, for example products, and category-like taxonomy, for example brands.

Multi language support is a lot trickier, however, I have good experiences with:

• xili-language

For thumbnails, use post thumbnail function, it can be enabled in your theme init with:

add_theme_support( 'post-thumbnails' );

I hope it helped!
