<%= link_to_named_routes :hello, [ :world, :foo, :bar ], :base_class => 'tabs' %>

<ul class="tabs depth-0">
<li class="active">
<a href="/hello">Hello!</a>
</li>
<li>
<a href="/world">World</a>
<ul class="tabs depth-1">
<li>
<a href="/foo">Foo</a></li>
<li>
<a href="/bar">Baz</a>
</li>
</ul>
</li>
</ul>
