How do I make the function codes for the WordPress menu?
<li class="navigation-item">
<a class="navigation-link" href="#">Example</a>
<ul class="navigation-dropdown">
<li class="navigation-dropdown-item">
<a class="navigation-dropdown-link" href="#">Example</a>
</li>
<li class="navigation-dropdown-item">
<a class="navigation-dropdown-link" href="#">Example</a>
</li>
</ul>
</li>
