I have setup up a custom list view with new products based on the products list view.
<block type="catalog/product_specials" name="product_new" template="catalog/product/list.phtml">
My problem is now the layered navigation do not appear in the left sidebar as on the default list view.
Is it possible to integrate layered navigation in a custom list view?
