Hello,

Thanks for the feedback and sorry for the late answer! You don’t need to use splitted CSS/JS files with the Flexible Content Dynamic Render. You can just enqueue a global custom CSS/JS files using the code available in the FAQ section: “How to enqueue new style/script files in the Flexible Content in PHP?”.

Here is a usage example:

add_action('acfe/flexible/enqueue/name=my_flexible', 'my_acf_flexible_enqueue', 10, 2);
function my_acf_flexible_enqueue($field, $is_preview){

    // Only in Ajax preview
    if($is_preview){

        wp_enqueue_style('my-style-preview', 'https://www.example.com/style-preview.css');

    }

    wp_enqueue_style('my-style', 'https://www.example.com/style.css');

}

Hope it helps!

Regards.
