On the post editing screen, after saving a post, you will notice that the checked categories are displayed on top, breaking the category hierarchy. This plugin removes that “feature”.
Additionally, it automatically scrolls to the first checked category.
Works with custom taxonomies too.

Category Checklist Tree

Simple and without configuration, it's just does what it says it does.



Works as expected

Really, I just can't understand why WordPress developers walk another way - this is, how it should be! :)
I have launched over 100 websites on WordPress - and they all have this plugin.
Thanks again!

Thanks!

Preserves the category hierarchy on the post editing screen

Gutenberg Editor already maintains the parent-child relationship when you select a category. So the child doesn’t move at the top in the category meta box. So this plugin isn’t required if you’re using the Gutenberg Editor.
Categories in Hierarchical Order plugin applies to WordPress Classic Post Editor only.
This plugin contains functionality to let you maintain default hierarchical order of categories when you select and save them for a post in your WordPress Admin Classic Post Editor.
The selected category/categories, to which a post belongs, are by default pushed at the top in the Category tab while saving the post. Whereas activating Categories in Hierarchical Order plugin will keep the position of selected category/categories unchanged as per their parent/child relationship.

Categories in Hierarchical Order

Does exactly what you expect from this plugin. Nice!

Works great!

Does exactly what should be the default option in Wordpress, great! Sorely needed if you have many categories (possibly with very similar names) and rely on a complex hierarchy.

Great!

Perfect

Why is this not part of the WordPress core yet? This plugin fixed my ugly looking category structure! Thanks guys!

Brilliant!
