/*
We will create a navigation menu like this:
{{ HTML::nav(array('login', 'register', 'wiki', 'forum', '/' => 'Home')) }}
 
Which will output:
<ul>
<li><a href="yourdomain.com/login" class="active">Login</a></li>
<li><a href="yourdomain.com/register">Register</a></li>
<li><a href="yourdomain.com/wiki">Wiki</a></li>
<li><a href="yourdomain.com/forum">Forum</a></li>
<li><a href="yourdomain.com">Home</a></li>
</ul>
 
Just make sure to load your macro.

 // We will have to set the url to equal the key instead
$url = is_numeric($key) ? $val : $key;

$menu = HTML::ul($nav, $attributes);
 // HTML::ul() performs htmlentities on the list by default, so we have to decode it back using HTML::decode()

 // Return the generated menu
 return $menu;
});
 
// Example.php
 
// Example 1
{{ HTML::nav(array('login', 'register', 'wiki', 'forum', '/' => 'Home')) }}
 
// Example 2
// What if you want to display a link based on a condition like Auth::check()
{{ HTML::nav(array(array(Auth::check(), 'logout', 'login'), 'register', 'wiki', 'forum', '/' => 'Home')) }}
// Now the login link will be displayed if user is not logged in and vice versa
