+## Prepending
+
+Because of Isotope's sorting functionality, prepending isn't as straight forward as might expect. However, it can be replicated fairly easy.  After prepending new content to the container, you can re-collect all the item elements and update their sorting order with the [`reloadItems` method](methods.html#reloaditems). Then trigger a re-layout, with the original DOM order.
