ANh chị xem video để biết cách làm nha còn code thì đính kèm dưới video:

Import thư viện owlcarousel (file functions.php) nhé anh chị:

add_action( 'wp_enqueue_scripts', 'standard_load_scripts' );
function standard_load_scripts() {
	wp_enqueue_script( 'owl-carousel-js', get_stylesheet_directory_uri(). '/js/owl.carousel.js', array( 'jquery' ), '1.0.0',false );
	wp_enqueue_style( 
        'add-owl-carousel-css', get_stylesheet_directory_uri(). '/js/owl.carousel.css', array(),'1.0.0'
    );
	}

add_action( 'wp_enqueue_scripts', 'standard_load_scripts' );

function standard_load_scripts() {

wp_enqueue_script( 'owl-carousel-js', get_stylesheet_directory_uri(). '/js/owl.carousel.js', array( 'jquery' ), '1.0.0',false );

wp_enqueue_style(

'add-owl-carousel-css', get_stylesheet_directory_uri(). '/js/owl.carousel.css', array(),'1.0.0'

);

}

Code widget đây:

<?php

     function __construct(){
        $widget_ops = array('description' => 'Home - Featured Product Category');
        $control_ops = array('width' => 300, 'height' => 300);
        parent::__construct(false,$name='Home - Featured Product Category',$widget_ops,$control_ops);
    }
	function form($instance){
		global $wpdb;
        //Defaults
        $instance = wp_parse_args( (array) $instance, array('title'=>'','product_ids'=>'') );
		$title = htmlspecialchars($instance['title']);
		$product_ids = htmlspecialchars($instance['product_ids']);
		
		?>
      	<p><label for="<?php echo $this->get_field_id('title'); ?>">Title: </label>  
        <input   name="<?php echo $this->get_field_name('title'); ?>" id="<?php echo $this->get_field_id('title'); ?>" value="<?php echo $title; ?>">
