navigate option groups

[KiaraGrouwstra]

one feature for which i find myself sometimes still using the (outdated?) mynixos.com is the ability to navigate to option groups, e.g. for programs.firefox.
at https://search.nixos.org/options, one might explicitly search for such a path, but cannot so much click-navigate into such a group.
it might be nice to have something like that for nixos-search as well.
