I am having trouble displaying the dropdown menu on my WordPress website. How can I make sure the dropdown menu appears properly?
functions.php
register_nav_menus( array(
'primary' => __( 'Primary Menu', 'TNCTR-OnePage' ),) );
Header.php
<div class="navbar-fixed">
<nav class="navbar-tp">
<div class="nav-wrapper">
<div class="container">
<a href="<?php bloginfo('url'); ?>" class="brand-logo logo"></a>
<?php
wp_nav_menu(array(
'menu' => 'primary',
'menu_class' => 'right hide-on-med-and-down'
));
?>
<?php
wp_nav_menu(array(
'menu' => 'primary',
'menu_class' => 'side-nav',
'menu_id' => 'mobilemenu',
'items_wrap' => '<ul id="slide-out" class="%2$s">%3$s</ul>'
));
?>
<a href="#" data-activates="slide-out" class="button-collapse"><i class="mdi-navigation-menu"></i></a>
</div>
</div>
</nav>
HTML ver.
