Mehrstufiges Bootstrap-Navigationsmenü in WordPress

Ich konvertiere eine statische Website, die mit Bootstrap in WordPress erstellt wurde. Hier ist mein Bootstrap Multilevel-Navigationsmenü-Code:

<section class="menuBar">
    <nav class="navbar navbar-expand-lg navbar-light" data-toggle="sticky-onscroll">
        <div class="container">
            <button class="navbar-toggler collapsed" type="button" data-toggle="collapse" data-target="#mainNavbar" aria-controls="mainNavbar" aria-expanded="false" aria-label="Toggle navigation">
              <span class="navbar-toggler-icon"></span>
            </button>

            <div class="navbar-collapse collapse" id="mainNavbar" style="">
              <ul class="navbar-nav">
                <li class="nav-item">
                  <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>

                </li>
                <li class="nav-item">
                  <a class="nav-link" href="contact.php">Contact Us</a>
                </li>
              </ul>
            </div>
            <a class="btn btn-red" href="#">Book Now</a>
          </div>
        </nav>
      </section>

Und es funktioniert gut für mich:  enter image description here 

Aber in WordPress habe ich WP_Bootstrap_Navwalker () für das Navigationsmenü verwendet. Ich habe depth => 3 gesetzt, aber es wird nicht wie erwartet ein mehrstufiges Menü angezeigt. Hier ist mein Code:

<?php
    wp_nav_menu( array(
        'theme_location'    => 'primary',
        'depth'             => 3,
        'container'         => 'div',
        'container_class'   => 'collapse navbar-collapse',
        'container_id'      => 'mainNavbar',
        'menu_class'        => 'navbar-nav',
        'fallback_cb'       => 'WP_Bootstrap_Navwalker::fallback',
        'walker'            => new WP_Bootstrap_Navwalker()
    ) );
?>

Aber es funktioniert nur für Dropdown. Es wird kein Untermenü des Untermenüs angezeigt. Wie kann ich dieses Problem beheben?

Hier etwas Interessantes für dich

SCHRITT 1 Füge ein Skript wie unten im Header ein (es ist immer besser, die Enqueue-Methode zu wählen. Ich brauche jemanden, der mir hilft, das unten stehende Skript in WordPress korrekt einzufügen. Die Abfrage sollte vor dem zweiten Skript ausgeführt werden.>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script>
$(document).ready(function () {
$('.dropdown-menu a.dropdown-toggle').on('click', function(e) {
  if (!$(this).next().hasClass('show')) {
    $(this).parents('.dropdown-menu').first().find('.show').removeClass("show");
  }
  var $subMenu = $(this).next(".dropdown-menu");
  $subMenu.toggleClass('show');


  $(this).parents('li.nav-item.dropdown.show').on('hidden.bs.dropdown', function(e) {
    $('.dropdown-submenu .show').removeClass("show");
  });


  return false;
});
});

</script>

SCHRITT 2 Füge das CSS wie folgt hinzu:

.dropdown-submenu {
  position: relative;
}

.dropdown-submenu a::after {
  transform: rotate(-90deg);
  position: absolute;
  right: 6px;
  top: .8em;
}

.dropdown-submenu .dropdown-menu {
  top: 0;
  left: 100%;
  margin-left: .1rem;
  margin-right: .1rem;
}
/* to show the arrow */
.dropdown-submenu a::after {
  transform: rotate(-90deg);
  position: absolute;
  right: 6px;
  top: .8em;
}
.dropdown-toggle a::after{
  transform: rotate(-90deg);
  position: absolute;
  right: 6px;
  top: .8em;
}

SCHRITT 3 Gehen Sie jetzt in die Walker-Klasse: Suchen Sie nach && 0 === $depth und entfernen Sie ihn. Stellen Sie auch sicher, dass
'depth' => 3

Jetzt sollte das Menü der 3. Ebene angezeigt werden. Möglicherweise ist ein zusätzliches CSS erforderlich.

Dies wird in der Kopfzeile addiert:

wp_nav_menu( array(
                'theme_location'    => 'primary',
                'depth'             => 3,
                'container'         => 'div',
                'container_class'   => 'collapse navbar-collapse',
                'container_id'      => 'bs-example-navbar-collapse-1',
                'menu_class'        => 'nav navbar-nav',
                'fallback_cb'       => 'WP_Bootstrap_Navwalker::fallback',
                'walker'            => new WP_Bootstrap_Navwalker(),
            ) );
