For displaying featured products with WooCommere the
[products visibility="featured"] or
[featured_products] shortcodes can be used. If your WooCommerce version is lower than 3.2 then you should use the latter.
The appearance of the displayed products depends on your active theme, the following examples are using Chap theme, but the shortcodes work with any theme as long as you’re using WooCommerce.
Displaying WooCommerce featured products using the products shortcode
[products limit="4" columns="4" visibility="featured" /]
WooCommerce featured products shortcode
[featured_products columns="3" per_page="3" /]
NotesThe old featured_products shortcode should be used for WooCommerce version 3.1 or lower.
