Hierarchical post types - parent and child CPTs/Pages

[rob-j-oliver]

Would love to see EmDash PR support hierarchical post types (and Pages), ala WordPress. Hierarchical: the parent page is on top, followed by child pages on a sub-level, which could again be followed by grand-child pages on a sub-sub-level.

Probably as a follow up PR - allowing duplicate child slugs as long as the parent pages CPTs have unique slugs, again ala WP.

Would imagine this would also impact those looking to migrate from WordPress.
