Hello!

To get a list of sub categories within the “kids-videos” category, you should be able to use get_terms() as below. Replace the number 1 in 'parent' => 1 to the ID of the “kids-videos” category.

$terms = get_terms(

    array(

        'taxonomy'   => 'category',

        'hide_empty' => true,

        'number'     => $per_page,

        'offset'     => $offset,

        'parent'     => 1

    )

);

Hi @sumon1068

I finally got this working, but it’s not an ideal solution. To remove the categories only from the editor after making the revision bcworkz suggested, you can change the first if statement to this:

if ( defined( 'REST_REQUEST' ) && REST_REQUEST && !current_user_can( 'manage_options' ) ) {

This is not an ideal solution because we’re hiding the categories on all REST requests without checking whether it’s on the WordPress Dashboard or not. But as long as your theme isn’t using REST requests to display categories on the front-end, this should work. And maybe someone will come up with a better solution.

Also, methods like is_admin() or WP_Screen::is_block_editor to check whether we’re on the Dashboard doesn’t work here because of the way REST requests work.

I believe the plug-in mentioned by @bizanimesh doesn’t filter categories on the WordPress Dashboard. It only works on the front-end. Please correct me if I’m wrong though.

I was looking into the code provided by @sumon1068 on your original post for a few hours now. And from what I found, it and the other plug-ins that you mentioned doesn’t work on Gutenberg.

For some reason, it starts working if I remove the if condition and have it as follows:

add_filter( 'list_terms_exclusions', 'yoursite_list_terms_exclusions', 10, 2 );
function yoursite_list_terms_exclusions( $exclusions, $args ) {
        return $exclusions . " AND t.slug NOT IN ( 'selected', 'editorial' )";
}

But this removes the categories from the front-end as well. So I haven’t really found a solution for Gutenberg yet.

Just wanted to post my findings.

Edit: Adding an if statement anywhere on the code before changing the $exclusions causes it to stop working. Even if I add the if statement in another function and add it to admin_init and add the filter from there.
