Wordpress short code to display all child page by parents ID

I'm working on a short code for loop through parents ID and display all child page, but I'm not quite sure how to make the loop and make it more custom.

Here's my code:
add_shortcode( 'home-page-listing', 'get_list' );

function get_list( $atts )
ob_start();
$atts = shortcode_atts( array(
'ids' => ''
), $atts );
if($atts['ids']!='')

$id_array = explode(',',$atts['ids']);
$homePages = new WP_Query( array(
'post_type' => 'page',
'post__in'=>$id_array,
'order' => 'ASC',
'orderby' => 'post__in',
'posts_per_page' => -1
) );
if ($homePages->have_posts())?>
<div class="">

<?php while ( $homePages->have_posts() ) : $homePages->the_post(); ?>
//here's html template code
<?php endwhile;
wp_reset_postdata(); ?>
</div>





Right now I can use [home-page-listing id=1,2,3,4] to display all select page ID, but I would like to make like this:

[home-page-listing id=1,2,3,4]

[home-page-listing parentID=4]


loop through all child page and display to the font, instead go check all the page id to display.

Thanks!

it's simple used post_parent Arguments of WP_Query. Please check below example

post_parent

WP_Query

$homePages = new WP_Query( array(
'post_type' => 'page',
'post_parent'=>$parentID,
'order' => 'ASC',
'orderby' => 'parent',
'posts_per_page' => -1
) );
