I had to display all the child categories products of the root category on a page with filtered navigation on the left column, but by default Magento does not display the root category products.
After some search and research I find the solution for this. It can be accomplished using Layout Update XML inside the CMS page. Not only layered nav but toolbar will also be displayed. For this we need to create a new CMS page or we can use any existing page where we want to display the products of the root category with filtered nav.
- Open Manage Category page in admin and choose the root category you want to display. Make sure that the category is Active and Is Anchor yes. Note down the category id.
- Create a new CMS page, CMS > Pages > Add New Page or Edit any existing one where you want to display the products.
- Fill the proper information in the required fields.
