I would like (as on other platforms) to be able to create many pages where in each one I show a product.

You can set up a "preview" image and associate one or more categories / tags to each page.

for example I could make 5 pages with watches and associate the category / tag watches, and another 5 with earrings (and associate with these the category / tag earrings)

once these pages have been set I would like to be able to go to another page and have a "container" element that shows me the preview of each page created, allowing me to filter them by category / tag

(maybe category and tag could also be used as menu items)

Currently I don't believe that this is possible, so if I wanted to create a sort of catalog I would have to manually manage both the product pages and the "container" page.

but this does not allow me to filter the products ...

can you implement something similar?
