Any link or tutorial for dropdown menu?
for example this is the default menu in advanced template
$menuItems = [
['label' => 'Home', 'url' => ['/site/index']],
['label' => 'About', 'url' => ['/site/about']],
['label' => 'Contact', 'url' => ['/site/contact']],
];
I want to add a sub-menu below About menu say "About Company", how I can do that?
Thanks in advance.
