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

Dropdown hierarchical category in WordPress post write panel or editing screen. It makes the categories or taxonomies list in a better UI which enables show/hide toggle of child categories. It comes with plugin settings page where you can select in what custom post type(s) the dropdown UI will be applied to.
The idea comes from default WordPress hierarchial post categories which looks not good. Imagine that there are a lot of child categories. After selecting child category then publishing or updating a post, the arrangement seems not pretty — the child categories moved away from its parent. This plugin tackles that situation.
