QueryLoop WooCommerce Variation Product

Hello. Are your attributes global ones or product specific ones?

Use this code to create a new custom dynamic tag for the Color variations you have created:

/**
 * Register Product Colors Dynamic Tag
 */
function register_product_colors_dynamic_tag() {
    if (!class_exists('GenerateBlocks_Register_Dynamic_Tag')) {
        return;
    }

    new GenerateBlocks_Register_Dynamic_Tag(
        [
            'title'    => __('Product Colors', 'generateblocks'),
            'tag'      => 'product_colors',
            'type'     => 'post',
            'supports' => ['source'],
            'return'   => 'product_colors_callback',
        ]
    );
}
add_action('init', 'register_product_colors_dynamic_tag');

/**
 * Product Colors Callback
 *
 * @param array  $options  The options.
 * @param object $block    The block.
 * @param object $instance The block instance.
 * @return string
 */
function product_colors_callback($options, $block, $instance) {
    if (!function_exists('wc_get_product')) {
        return '';
    }
    
    $product = wc_get_product(get_the_ID());
    
    if (!$product || !$product->is_type('variable')) {
        return '';
    }
    
    $colors = $product->get_attribute('Color');
    
    if (!$colors) {
        return '';
    }
    
    // Replace pipes or commas with slashes
    $colors = str_replace(' | ', ' / ', $colors);
    $colors = str_replace(', ', ' / ', $colors);
    
    return GenerateBlocks_Dynamic_Tag_Callbacks::output($colors, $options, $instance);
}

In your query loop, insert a GB text block and open dynamic tags. The last entry from the Post is called Product Colors.

Select that and check in the front end.

No, it will also show Red / Blue for example, as you stated in your image.

Sorry but that would require custom development which is out of scope of the current support forum. Hope you understand!
