Show Only Selected Custom Posts in a Page from Meta Box

// meta box that creates checkbox list with a list of 'objects' custom post type post titles 

$args = array('post_type' => 'objects', 'posts_per_page' => -1);
$objects = get_posts( $args );
$post_ids = wp_list_pluck( $objects , 'ID' );
$object_titles = wp_list_pluck( $objects , 'post_title' );
$combined_array = array_combine($post_ids, $object_titles);  // create an associative array where ids are key and titles are value

piklist('field', array(
'type' => 'checkbox'
,'field' => 'object_list'
 ,'label' => __('Object List', 'bbhs') 
,'description' => 'The object lists that will be visible under sub-categories only'
,'attributes' => array(
  'class' => 'object_list_checkbox'
)
,'choices' => $combined_array
));


// using code in query 

$selectedids = get_post_meta( $post->ID, 'object_list' );

	if($selectedids) {
		$args = array(
			'post_type' => 'objects',
			'post__in' => $selectedids
		);
	} else {
		echo '<div style="display:block;overflow:hidden; margin: 50px auto;"><h4>No Objects Selected to show</h4></div>';
	}
	
	$objects = new WP_Query( $args );
	
	if($objects->have_posts()) {
		echo '<div class="objects_lists">';
		// The Loop
		while ( $objects->have_posts() ) {
		
		...... 
						
	
// pretty easy, huh?

Suppose, I have two custom post type 'sections' & 'objects'. Now that I want to show selected 'objects' at the bottom of every 'section' page (single-sections.php) and the selection will be done when create a new 'section' from a checkbox in 'select' post type. The above code does this easily.
