It's always been a pain in the @$$ to see only 20 item in category. If i have 30, it paged on 2 pages, i hate that. If WordPress had a preference for that. So the question, Hot to list ALL the category, whatever the number... if i have 200, list them all, no paging. I inspect edit-tags.php and could not find "show_item=20" of something like that
The question, how to make edit-tags.php show 9999 item (or unlimited) of have a plugin to customize that without hacking the WP core file.
I think the magic is happening here, but changing 20 to 999 dont change anything
add_screen_option( 'per_page', array( 'label' => $title, 'default' => 20, 'option' => 'edit_' . $tax->name . '_per_page' ) );
It's for product attribute in woocommerce.
