How can I hide categories in wp-admin edit page?

I know I can hide categories from the front pages with 'exclude' like this:

<?php wp_list_categories('title_li=&orderby=id&hide_empty=0&exclude=1,13,78,79,3023'); ?>

What I need to do now though, is hide them on the add/edit post pages on the backend. I need to leave these categories in place for legacy... but I want to limit my authors to choosing only the new categories I now have.

Is there a way I can hide those, perhaps something I could put in theme/function.php or something like that?

Thanks,  Chris

I don't believe that there is any way to do that through wordpress.  There isn't anything in the database that you denotes if a category is active or has a daterange for the category begin or category end. It would be nice though.

Hover the way that those items are displayed on the page could be changed. In the add/edit post pages those items are listed as

category-id

ie

<li class="popular-category" id="category-9"><label class="selectit"><input type="checkbox" id="in-category-9" name="post_category[]" value="9"> Newletters</label></li>

create a file in your themes folder in a directory called css for example: your-theme/css/hidden-categories.css and in it place the categories you don't want people to choose like below

#category-9, #category-15
{
display: none;
}


then include that css into the site via your themes function.php file. Add this to the bottom of functions.php in your themes file.

wp_register_style('my-style', get_bloginfo( 'stylesheet_directory' ) . '/css/hidden-categories.css', false, 0.1);
wp_enqueue_style( 'my-style' );
