And it's working fine for me:
But to in WordPress, I have used WP_Bootstrap_Navwalker() for the navigation menu. I have put depth => 3 but it's not showing multi level menu as expected. Here is my 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()
) );
?>
But it's just working for dropdown only. It's not showing submenu of submenu. How can I fix this problem?
Solution
Here some thing interesting for you
STEP 1 add a script to header like below ( it's always better go for the enqueue method . i need some one to help me with properly adding the below script in WordPress way .jquery should run before the 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>
STEP 2 Add the css like below :
.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;
}
STEP 3
Now go inside the walker class :
search for && 0 === $depth and remove it. Also make sure that
'depth' => 3
Now it should start showing the 3rd level menu . some additional css might be required.
This is being added up in header :
wp_nav_menu( array(
'theme_location' => 'primary',
'depth' => 3,
'container' => 'div',
'container_class' => 'collapse navbar-collapse',
'container_id' => 'bs-example-navbar-collapse-1',
'menu_class' => 'nav navbar-nav',
'fallback_cb' => 'WP_Bootstrap_Navwalker::fallback',
'walker' => new WP_Bootstrap_Navwalker(),
) );
OTHER TIPS
For me it works perfect when I remove this line of code:
if (!$(this).next().hasClass('show')) {
$(this).parents('.dropdown-menu').first().find('.show').removeClass("show");
}
as in bootstrap v4 the .dropdown-submenu class doesn't exist (atleast in mine it doesn't) so if you want for your sub-menus to closes when one click outside of the dropdown just change .dropdown-submenu .show to .dropdown-menu .dropdown-menu.show in the above solution,and make it like in the snippet below:
$('.dropdown-menu a.dropdown-toggle').on('click', function(e) {
if (!$(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-menu .dropdown-menu.show').removeClass("show");
});
return false;
});
