var Nav = $nav.data('hcOffcanvasNav');

.getSettings()

Returns current settings.

var currentSettings = Nav.getSettings();

}

.update(options, updateDOM)

Nav.update({
  disableAt: 1024,
  navTitle: 'All pages'
});

Updates nav DOM. You don’t have to pass empty settings object. The method is smart. Use this when original nav has been altered.

Nav.update(true);

Updates both settings and nav DOM. Use this when original nav was altered and you want to update some specific settings as well.

Nav.update({
  disableAt: 1024,
  navTitle: 'All pages'
}, true);

.open(level, index)

Opens the nav if closed.

Nav.open();

Open the nav along with a specific sub menu. Each level sub menu has its own index that is relative to that level, not the parent menu.

Nav.open(2, 1);

Above code will open to the nested menu in the example structure bellow:

<nav>
  <ul><!-- Level: 0 -->
    <li></li>
    <li>
      <ul><!-- Level: 1, Index 0 -->
        <li>
          <ul><!-- Level: 2, Index: 0 -->

WordPress data attributes integration

To make your WordPress theme nav data ready, just place this code to your functions.php file. It will work out of the box. Don’t assign this custom Walker to your wp_nav_menu arguments. You don’t need to be worry if your own custom Walker is already used, this code will take care of the whole thing.

/*
 * Adds menu data support for HC Off-canvas Nav
 */

$hc_nav_menu_walker;

class HC_Walker_Nav_Menu extends Walker_Nav_Menu {

  public function start_lvl(&$output, $depth = 0, $args = array()) {
    global $hc_nav_menu_walker;
    $hc_nav_menu_walker->start_lvl($output, $depth, $args);
  }

  public function end_lvl(&$output, $depth = 0, $args = array()) {
    global $hc_nav_menu_walker;
    $hc_nav_menu_walker->end_lvl($output, $depth, $args);
  }

  public function start_el(&$output, $item, $depth = 0, $args = array(), $id = 0) {
    global $hc_nav_menu_walker;

    $item_output = '';

    $hc_nav_menu_walker->start_el($item_output, $item, $depth, $args, $id);

    if ($item->current_item_parent) {
      $item_output = preg_replace('/<li/', '<li data-nav-active', $item_output, 1);
    }

    if ($item->current) {
      $item_output = preg_replace('/<li/', '<li data-nav-highlight', $item_output, 1);
    }

    $output .= $item_output;
  }

  public function end_el(&$output, $item, $depth = 0, $args = array(), $id = 0) {
    global $hc_nav_menu_walker;
    $hc_nav_menu_walker->end_el($output, $item, $depth, $args, $id);
  }
}

add_filter('wp_nav_menu_args', function($args) {
  global $hc_nav_menu_walker;

  if (!empty($args['walker'])) {
    $hc_nav_menu_walker = $args['walker'];
  }
  else {
    $hc_nav_menu_walker = new Walker_Nav_Menu();
  }

  $args['walker'] = new HC_Walker_Nav_Menu();

  return $args;
});
