Sample data pages contain the same contents and shortcode elements, which are on demo pages. The only difference between sample-data and demo are images, the number of posts/products, and menu items.
Images: Images used on our demo pages are commercial images, which are licensed to use on our demo sites only. So, we can’t redistribute them for any purpose. So, sample data contains placeholder images instead.
Post/Product and Related Taxonomy Terms: There is a limited number of posts and products provided in the sample data because these items are to be added by users. Therefore categories and tags are also limited.
Menu: The menu on our demo site is to display different styles and layouts of different sections, pages, and content of the theme. Therefore, this menu is not of any use in sample-data. However, if you need a similar menu, you can create it.
