Instead of sliding the content to the next page and hiding the main list items, why not use a sliding down or collapsible list allowing the nested list to appear below the main item instead of the next page. This addresses the issue of allowing a user to still see the main list items and nest items on one page and eliminating the need to go back and forth between pages to see the nested list and primary list.
