Init the Gutenberg editor

Web development WordPress
1

I tried many methods to fix this but with no results. Does anybody know how to init the Gutenberg editor on a custom admin page? I’m really in need of fixing it since I can’t update the posts. Any help is welcomed.

Start by registering a Gutenberg WordPress custom type. The process is fairly easy and involves adding the following the code snippet.

/*Register WordPress  Gutenberg CPT */
function cw_post_type() {

    register_post_type( 'portfolio',
        // WordPress CPT Options Start
        array(
            'labels' => array(
                'name' => __( 'Portfolio' ),
                'singular_name' => __( 'Portfolio' )
            ),
            'has_archive' => true,
            'public' => true,
            'rewrite' => array('slug' => 'portfolio'),
            'show_in_rest' => true,
            'supports' => array('editor')
        )
    );
}

add_action( 'init', 'cw_post_type' );

add the show_in_rest key and set it to true via your custom post type.
