<?php $_menu = $this->renderCategoriesMenuHtml(0,'level-top') ?>
<?php if($_menu): ?>
<div class="nav-container">
    <ul id="nav">
        <?php foreach ($this->getStoreCategories() as $_category): ?>
            <?php if(stristr('YOURID1,YOURID2,YOURID3', $_category->getId()) === FALSE)   : ?>

        <?php endforeach ?>
    
        <?php// echo $_menu ?>
    </ul>
</div>
<?php endif ?>
