Hi @fress0,
To make sure I understand your request, are you looking to separate your products into two categories, ‘New Products’ and ‘Second Hand Products’, and display them on two different pages, each showing only products related to its respective category? Additionally, you want the sidebar to display only products from the relevant category on each page? If so, this will involve some customization.
I can guide you on the general approach, but please note that detailed customization is beyond the scope of this forum, which focuses on WooCommerce core issues.
First, create two product categories by following these instructions: https://woocommerce.com/document/managing-product-taxonomies/#how-to-add-edit-product-categories. Once you’ve created the categories, you can edit your products and assign them to the appropriate category.
Then, create two separate pages, ensuring that only the products from the respective category appear on each. You can disable the global sidebar for each page and set up a custom sidebar for each page. This can also be done using the Divi Theme Builder, as you have it installed, or you can use Elementor templates for custom layouts.
If this process seems overwhelming, you can hire a professional from codeable.io to assist you with the customization.
