I have several sub-categories set up. Everything displays properly as far as nesting (see below) when creating a new post.
Category 1
–Sub Category 1
–Sub Category 2
–Sub Category 3
Category 2
etc
After I select a sub-category, then go back and edit a post, the sub category that I check shows up like this (note how it’s not nested under Category 1):
(checkmark) Sub Category 2
Category 1
–Sub Category 1
–Sub Category 3
Category 2
etc
Is this a bug in WordPress 3.1.2? Can someone tell me how to fix it? I don’t remember it doing this when I was running 3.0.5 (but there’s a chance it could have).
This “feature” has been in WP for quite a while.
You can disable it by installing this small plugin:

It was mentioned that scribu’s plugin hasn’t been updated in four years. However, the plugin is fairly simple and the most important part is this:
That’s what the plugin mainly does â plus some JavaScript to scroll to the first category checkbox that is checked. But that’s just for convenience.
