Add in functionality for pages to be filtered only

[kuwts]

I'm building a directory using Pagefind, and love the functionality, it would be great if I could have items listed all the time and have buttons users could use for filter and sort.

Hey @kuwts 👋

This is the sort of thing that can be built using Pagefind's JS API — it's unlikely to be added as a feature to the Default UI though, as that focuses on the search use-case rather than filtering/facets.

I have a long-term desire to get back to the "Modular UI" that has been in progress for a while, which would be a great home for this functionality. No timeline for wrapping that up though, I'm afraid.
