Hi! I’m the author of WP-dTree, and I’ve just released Content Trees: a fresh take on collapsible navigation for WordPress archives, pages, categories and tags.

It works with blocks, classic widgets and shortcodes. Visitors can explore branches without leaving the page, with post titles loaded as needed. If you already use WP-dTree, you can can try this alongside it - your existing widgets and settings stay intact.

It’s free and open source: https://wordpress.org/plugins/content-trees/

I’d love feedback, especially from people with years of posts or a deep page hierarchy. Is it straightforward to set up, and does it fit comfortably into your theme?
