Hi, please try this

Add to functions.php

/**

class Razorback_Walker_Page_Selective_Children extends Walker_Page {
/**
* Walk the Page Tree.
*
* @global stdClass WordPress post object.
* @uses Walker_Page::$db_fields

*/
function walk( $elements, $max_depth ) {
global $post;
$args = array_slice( func_get_args(), 2 );
$output = '';

/* invalid parameter */
if ( $max_depth < -1 ) {
return $output;
}

/* Nothing to walk */
if ( empty( $elements ) ) {
return $output;
}

/* Set up variables. */
$top_level_elements = array();
$children_elements = array();
$parent_field = $this->db_fields['parent'];
$child_of = ( isset( $args[0]['child_of'] ) ) ? (int) $args[0]['child_of'] : 0;

/* Loop elements */
foreach ( (array) $elements as $e ) {
$parent_id = $e->$parent_field;
if ( isset( $parent_id ) ) {
/* Top level pages. */
if( $child_of === $parent_id ) {
$top_level_elements[] = $e;
}
/* Only display children of the current hierarchy. */
else if (
( isset( $post->ID ) && $parent_id == $post->ID ) ||
( isset( $post->post_parent ) && $parent_id == $post->post_parent ) ||
( isset( $post->ancestors ) && in_array( $parent_id, (array) $post->ancestors ) )
) {
$children_elements[ $e->$parent_field ][] = $e;
}
}
}

/* Define output. */
foreach ( $top_level_elements as $e ) {
$this->display_element( $e, $children_elements, $max_depth, 0, $args, $output );
}
return $output;
}
}

Add to any template file with a php extension:

$walker = new Razorback_Walker_Page_Selective_Children();
wp_list_pages( array(
'title_li' => '',
'walker' => $walker,
) );

Will recognize the child_of parameter.

$walker = new Razorback_Walker_Page_Selective_Children();
wp_list_pages( array(
'title_li' => '',
'child_of' => 1283,
'walker' => $walker,
) );
