Cannot show dropdown menu in level depth 3

i cannot see dropdown menu in level depth 3 .
is this the bugs ?

Perhaps this is what you’re looking for?

And no it’s not a bug

yes you right . Tanks for replay

this is how to me load the menu

if (has_nav_menu('primary_navigation')) :
          wp_nav_menu(['theme_location' => 'primary_navigation', 'walker' => new Nav\SageNavWalker(), 'menu_class' => 'nav navbar-nav', 'depth'=>3]);

i put the index ‘depth’ there.
Actually the code return the html code for child menu , but i can’t see the third level of menus on frontend.

maybe i need some add class or something else ?


Multilevel dropdown support was removed in Bootstrap 3. Wordpress will generate the markup but it will not be displayed.

I found the solutions , and it’s work on my side
