How to increase Number of carousel items that should move on animation?

Hi @heshamg please try adding this to your functions.php:

function metaslider_flex_params($options, $slider_id, $settings) {
    if ($slider_id == 123) { // check for slider ID (optional)
        $options['move'] = 3;
    } 
    return $options;
} 
add_filter('metaslider_flex_slider_parameters', 'metaslider_flex_params', 10, 3);

Perfect! .. It works just fine ??
