Obrigado por responder, o jeito foi esse mesmo criar uma página html, e lincar ao opencart...fiz assim: no header.tpl
<?php if ($categories) { ?>
<div id="menu">
<ul>
<li><a href="página.html/">link name</a></li> //link before categories
<?php foreach ($categories as $category) { ?>
<li><a href="/<?php echo $category['href']; ?>"><?php echo $category['name']; ?></a>
<?php if ($category['children']) { ?>
<div>
<?php for ($i = 0; $i < count($category['children']);) { ?>
<ul>
<?php $j = $i + ceil(count($category['children']) / $category['column']); ?>
<?php for (; $i < $j; $i++) { ?>
<?php if (isset($category['children'][$i])) { ?>
<li><a href="/<?php echo $category['children'][$i]['href']; ?>"><?php echo $category['children'][$i]['name']; ?></a></li>
<?php } ?>
<?php } ?>
</ul>
<?php } ?>
</div>
<?php } ?>
</li>
<?php } ?>
<li><a href="página.html">link name</a></li> //link after categories
</ul>
</div>
<?php } ?>
