Display List of Product from a single category of product post type

I am creating an e-Commerce website, I used Jigoshop plugin. Now I want to create a menu for the List of Product/Post from a Single category of a custom Post Type which is “Product”. I tried using a plugin but the categories from “Product” post type are not included on the list.

for example..

From the category “Package” it should display a list of posts/products from the category “Package”. I am planning it to display as navigation menu..

Is there a loop for it?

Thanks 🙂
