At the top of the page with our collections https://en.numista.com/vous/index.php there is a filter to select the type of objects for which information is displayed (or for all at once).
This filter always show options with all types, whether we collect the type or not. I think it makes not sense to see the unwanted types here.
My suggestion is to not show a type in the filter options if the following two conditions are true:
- I deselect the type in the “Define my wishes > 1” section of https://en.numista.com/souhaits/vos_souhaits.php page and
- I do not have any objects of the type in my collection and my swap list.
