Кому интересно, тут и AJAX сделал

<div class="modal-items">
				<?php
					$cart_items = WC()->cart->get_cart();
					foreach( $cart_items as $cart_item_key => $item ) { ?>
					
					<div class="left col-md-3">
					<div class="product-image"><!-- Make sure ot check if it's a gallery, if so, get its first image -->
					<?php echo $item['data']->get_image(); ?>
					</div>
					</div>
					<div class="right col-md-8">
					<h4 class="product-name"><?php echo $item['data']->get_name(); ?></h4>
					<div class="product-information">
					<span class="product-quantity"><?php echo $item['quantity'] . 'x' ?></span>
					<span class="product-price"><?php echo $item['data']->get_price_html(); ?></span>
					</div>
					<?php
					echo apply_filters( 'woocommerce_cart_item_remove_link', sprintf(
					'<a href="%s" aria-label="%s" data-product_id="%s" data-product_sku="%s">X</a>',
					esc_url( wc_get_cart_remove_url( $cart_item_key ) ),
					__( 'Remove this item', 'woocommerce' ),
					esc_attr( $item['product_id'] ),
					esc_attr( $item['data']->get_sku() )
					), $cart_item_key );
					?>
					</div>
					<?php } ?>
				</div>

Далее создаем точно такой же фрагмент в functions.php:

function modal_add_to_cart_fragments( $fragments ) {

    ob_start();

    ?>
	<div class="modal-items">
	<?php
					$cart_items = WC()->cart->get_cart();
					foreach( $cart_items as $cart_item_key => $item ) { ?>
					
					<div class="left col-md-3">
					<div class="product-image"><!-- Make sure ot check if it's a gallery, if so, get its first image -->
					<?php echo $item['data']->get_image(); ?>
					</div>
					</div>
					<div class="right col-md-8">
					<h4 class="product-name"><?php echo $item['data']->get_name(); ?></h4>
					<div class="product-information">
					<span class="product-quantity"><?php echo $item['quantity'] . 'x' ?></span>
					<span class="product-price"><?php echo $item['data']->get_price_html(); ?></span>
					</div>
					<?php
					echo apply_filters( 'woocommerce_cart_item_remove_link', sprintf(
					'<a href="%s" aria-label="%s" data-product_id="%s" data-product_sku="%s">X</a>',
					esc_url( wc_get_cart_remove_url( $cart_item_key ) ),
					__( 'Remove this item', 'woocommerce' ),
					esc_attr( $item['product_id'] ),
					esc_attr( $item['data']->get_sku() )
					), $cart_item_key );
					?>
					</div>
					<?php } ?>
	</div>
    <?php
    $fragments['.modal-items'] = ob_get_clean();
    return $fragments;
}

add_filter( 'woocommerce_add_to_cart_fragments', 'modal_add_to_cart_fragments', 10, 1 );

Если знаете как можно сделать проще, то буду очень Благодарен !
