Et ça marche bien pour moi: 
Mais dans WordPress, j'ai utilisé WP_Bootstrap_Navwalker () pour le menu de navigation. J'ai mis la profondeur => 3 mais cela ne montre pas le menu à plusieurs niveaux comme prévu. Voici mon 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()
) );
?>
Mais cela ne fonctionne que pour le menu déroulant. Cela ne montre pas le sous-menu du sous-menu. Comment puis-je résoudre ce problème?
Voici quelque chose d'intéressant pour vous
ÉTAPE 1 ajouter un script à l’en-tête comme ci-dessous (il est toujours préférable d’utiliser la méthode de mise en file d’attente. J’ai besoin de quelqu'un pour m'aider à ajouter correctement le script ci-dessous dans WordPress. Jquery devrait être exécuté avant le second script>
<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>
ETAPE 2 Ajoutez le css comme ci-dessous:
.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;
}
ÉTAPE 3 Maintenant, entrez dans la classe de randonneur: recherchez && 0 === $depth et supprimez-le. Assurez-vous également que'depth' => 3
Maintenant, il devrait commencer à afficher le menu de 3ème niveau. des css supplémentaires peuvent être nécessaires.
Ceci est ajouté dans l'en-tête:
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(),
) );
