create category template for nested menu

Is it possible to create a template to output nested categories, for example to create a collapsable menu. e.g.

<ul>
  <li><a>shirts</a>
    <ul>
      <li><a>long sleeve</a></li>
      <li><a>short sleeve</a></li>
    </ul>
  </li>
  <li><a>trousers</a>
    <ul>
      <li><a>jeans</a></li>
      <li><a>chinos</a></li>
    </ul>
  </li>
</ul>

The category templates aren't recursive like the navigation templates (although we should add an option for that), so I'm not sure there's a great way to output a nested list just now.

OK Drew thanks for response.

This is how I'm considering getting around that incase it's useful to anyone.

$cats = perch_categories(array('category' => 'Products', 'skip-template' => true));
$cats_menu = array_filter($cats, function($var) {
    return $var['catDepth']===1;
});
array_walk($cats_menu, function(&$value) use($cats) {
    $value['children'] = array_filter($cats, function($var) use($value) {
        return $var['catParentID']===$value['catID'];
    });
});
