Since breadcrumbs depend on the page you are in, it needs to be dynamically created for each page.
So the approach is to query it in each page as they are created and pass it on to the Breadcrumb component.
ploneBreadcrumbs(_path: { eq: $path }) {
items {
_id
_path
title
}
}
This data can be appropriately styled and used in a breadcrumb bar.
