Display a tag before the menu list content

Question

Is that possible to insert a text before the menu items? In this case, I want to lead a <h3> tag for the list content (like a menu title). I tried the if/else to recognize that the menu have content and show the title. But if the menu have no content, so it should not have to display the title.

Here it is:

$args = array(
  'menu'        => 'Destination • South America',
  'echo'        => false,
  'fallback_cb' => '__return_false'
);

if (empty($args)) {
  echo "<li></li>";
}else{
  echo "<h3>South America</h3>";
}
echo strip_tags(wp_nav_menu( $args ), '<li><a>');

Because I have content, so It should output:

South America
Argentina
Brazil
Chile
Colombia
Equador
Uruguay
Venezuela

If I would not have any content, so it should not display the South America

Thank you!

Put this function into your theme's function.php file.

function is_tree($pid) { // $pid = The ID of the page we're looking for pages underneath
    global $post;
    $anc = get_post_ancestors( $post->ID );
    foreach($anc as $ancestor) {
            if(is_page() && $ancestor == $pid) {
                    return true;
            }
    }
    if(is_page()&&(is_page($pid))) { return true; /*we're at the page or at a sub page*/ }
    else { return false; /*we're elsewhere*/ }
}

Then wrap your code in:

<?php
  // put the parent id or in this case, South America's id as the parent-id
  if(is_tree('parent-id')) {
    // output your menu
  }
?>
