This WooCommmerce featured product plugin enables you to display products based on categories with the help of shortcodes. This is also a very easy plugin to use and set up. All you have to do is find the slug of the desired category whose featured products you want to display on the homepage. Use the shortcode:
[featured_products_by_category cat=”your-selected-cat-slug”] in the page or widget section.
You can also limit the number of products shown per page by using the shortcode:
[featured_products_by_category cat=”your-selected-cat-slug” limit=4]
