## Code

```php
// Category slugs to show on the blog page, for example array( 'news' ).
$wpide_blog_categories = array();

add_action( 'pre_get_posts', function ( $query ) use ( $wpide_blog_categories ) {
    if ( is_admin() || ! $query->is_main_query() || ! $query->is_home() || ! $wpide_blog_categories ) {
        return;
    }

    $query->set( 'category_name', implode( ',', array_map( 'sanitize_title', $wpide_blog_categories ) ) );
} );
```

## Notes

The list is empty by default, which changes nothing. Add category slugs; posts from other categories still appear in their archives, search and feeds.
