I want to display a list of child and sibling pages.
Right now I’m using the “Relationship” field in ACF – and have the child pages choosing the parent page.
Is there a way to display a list of all pages that have the current page listed as a parent?
Along the same lines, can I also grab a list of all sibling pages?
I personally would set up bidirectional relationship fields using either code or a plugin.
Without this you need to do reverse relationship queries as described here https://www.advancedcustomfields.com/resources/querying-relationship-fields/
