Yes, we understand, but as we mentioned, we are not able to implement this feature because it will require a full rework of how the shop page work. And we can’t do this because shopping functionality comes with WooCommerce plugin and we are not able to customize the plugin. When you scroll down on the page you sent, you URL becomes like this http://royaldesign.se/Mobler.aspx#3 and when you visit it in a new window, it will load all products from 3 pages.
In the WooCommerce, if you visit this page https://woodmart.xtemos.com/shop/page/3/ it will load products from the third page only. It will not load ALL products from first to third page as you want. And that is why we are not able to implement this function without customizing the WooCommerce plugin a lot.
Hope you understand our explanation.
