To sort subpages, click Page Properties > Sort Subpages.

Sorting subpages allows you to rearrange your subpages for a more natural flow or to give higher priority to specific pages. To sort subpages, you must first be on the Parent Page. Clicking Sort Subpages opens a window that will list all the subpages of the current parent page. To rearrange, click on the desired page and click move up or move down. When finished, click Save and Perpetua will reorganize the pages accordingly. These pages will automatically rearrange in all Sub Page Boxes and in the Global Site Map.
