Hello,
Thanks for the topic.
Your site under maintenance mode, so I can’t check it.
Menu can’t be imported because WP does not support custom menu options, you need to create own menu. Please read more https://www.8theme.com/demo/docs/woopress/#!/primary_menu
Pages can be imported using .xml files (Tools > Import > WordPress). We included all the demo versions to XML files folder of theme package.
You need to create own categories and products and upload images, because we provide only a few elements as examples.
Woocommerce documentation can be useful – https://docs.woocommerce.com/documentation/plugins/woocommerce/getting-started/setup-products/
https://docs.woocommerce.com/document/managing-product-taxonomies/
Feel free to ask if you have any other questions.
Regards
