I found a question like this on stackoverflow.com, I put that code in Navigation.php but not work. Anyone?
Solution
What prevents you from just filter your collection by adding category filter?
$yourProductCollection = Mage::getModel('catalog/product');
// ->addAtributeToSelect(... your custom needs
// ->addAtributeToFilter(... your custom needs
$category = Mage::getModel('catalog/category')->load($categoryId);
$yourProductCollection->addCategoryFilter($category);
? And render your product collection in your custom template ?
