Hide Some Categories in Post Editor

I run a multi author blog. I want authors not to be able to publish posts under some categories(Suppose ‘selected’, ‘editorial’). So I want to hide them in post editor.

I tried this code:

add_filter('list_terms_exclusions', 'yoursite_list_terms_exclusions', 10, 2);
function yoursite_list_terms_exclusions( $exclusions, $args ) {
  global $pagenow;
  if (in_array($pagenow,array('post.php','post-new.php')) && 
     !current_user_can('manage_options')) {
    $exclusions = " {$exclusions} AND t.slug NOT IN ('selected','editorial')";
  }
  return $exclusions;
}

But it is not working. I used this code too:

function hide_categories_for_specific_user( $exclusions, $args ){    
if (!current_user_can('manage_options') ) {    
   // IDs of terms to be excluded
   $exclude_array = array("5","6"); // CHANGE THIS TO IDs OF YOUR TERMS    
   // Generation of exclusion SQL code
   $exterms = wp_parse_id_list( $exclude_array );
   foreach ( $exterms as $exterm ) {
           if ( empty($exclusions) )
                   $exclusions = ' AND ( t.term_id <> ' . intval($exterm) . ' ';
           else
                   $exclusions .= ' AND t.term_id <> ' . intval($exterm) . ' ';
   }    
   // Closing bracket
   if ( !empty($exclusions) )
       $exclusions .= ')';    
   // Return our SQL statement
   return $exclusions;    
  }
}    
 // Finally hook up our filter
 add_filter( 'list_terms_exclusions', 'hide_categories_for_specific_user', 10, 2 );

It works in the post editor but it breaks category widget in the front-end for non-admin users.

I used several plugins for that. “Restrict Categories, Author category” etc. But no luck. I am currently hiding them using css :nth-of-type. But works for add new post but it breaks when authors edit their post.

Can anyone help me?
