Hi,

In Odoo, product pages are dynamically generated and do not appear under Website → Pages, which only lists static pages. This is why you cannot see them in the Pages menu or duplicate them like regular website pages. When you edit a product page, you are actually modifying a QWeb template (usually product.template) rather than a standard page object. To duplicate or customize product pages, you need to work with these templates in developer mode or create custom layouts using snippets, blocks, or per-category templates, rather than expecting a standard page duplication feature.

Hope it helps
