If you have more than one category associated with a post, how do you tell which category takes precedence? This plugin gives you the ability to promote the category to the main one on the post edit page.
This gets stored in post meta for later use. Soon, I will add some simple functions that will allow you to get the main category on the front end.
Use
<ul>
<li>You can use the shortcode [rs_print_main] inside the post to print out the category title.</li>
<li>In the theme, you can use rs_get_main_category_id( $post_id ) to return (not print) the id of the main category.</li>
</ul>

RS Simple Category Selector

Gives you the ability to promote categories associated with a post.

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
