Whitelisting of Gutenberg Core blocks in JCORE®

Why whitelisting?

To control what content the customer/user can add in the Guternberg-editor, JCOre hides by default all Core Guternberg blocks and only shows the ones whitelisted in 'blocks.php'.

$whitelisted_blocks = apply_filters(
        'jcore_whitelisted_gutenberg_blocks',
        array(
            'core/paragraph',
            'core/heading',
            'core/list',

To add more blocks in your child theme, use this filter in your theme functions-file:

add_filter(
    'jcore_whitelisted_gutenberg_blocks',
    function( $blocks ) {
        $blocks[] = 'core/post-title';
        $blocks[] = 'core/post-date';
        $blocks[] = 'core/pullquote';
        $blocks[] = 'core/quote';
        $blocks[] = 'core/media-text';
        return $blocks;
    }
);
