How to load / show post on a page with multiple rows and columns

Dear @Ismael,

However, I don’t fully understand the part regarding the manual excerpt.

I’ve added the following snippet, and now the excerpt correctly shows the content from the first ALB text block ([av_textblock]), even if the manual excerpt field is empty:

add_filter( 'get_the_excerpt', 'custom_alb_excerpt_fallback', 20, 2 );
function custom_alb_excerpt_fallback( $excerpt, $post ) {
    if ( ! $excerpt && $post instanceof WP_Post ) {
        $raw_content = $post->post_content;

        // Extrahiere den ersten ALB Textblock (Shortcode [av_textblock])
        if ( preg_match( '/\[av_textblock.*?\](.*?)\[\/av_textblock\]/s', $raw_content, $matches ) ) {
            $inner = wp_strip_all_tags( $matches[1] ); // HTML entfernen
            $excerpt = wp_trim_words( $inner, 30, '...' ); // Kürze auf 30 Wörter
        }
    }

    return $excerpt;
}

Would you consider this a valid solution? Or is there any reason not to use such a fallback?
