I’m attempting to create customized menu nav walker. I added beneath code
perform display_element( $aspect, &$children_elements, $max_depth, $depth=0, $args, &$output )
{
$id_field = $this->db_fields['id'];
if ( is_object( $args[0] ) ) {
$args[0]->has_children = ! empty( $children_elements[$element->$id_field] );
}
return mum or dad::display_element( $aspect, $children_elements, $max_depth, $depth, $args, $output );
}
Because of this I can use if ( $args->has_children ) assertion in my start_el perform, sadly the identical code does not appear to be working in end_el perform.
Total code:

Am I doing one thing flawed?
