To change the order of pages, you must first access their host page.

1. Start by going to the desired page, turning on edit mode by clicking on “Show actions” button, and clicking on "Organize pages" from the navigation menu on the left. 
2. You can change the order of pages in two different ways. One way is to change the order of pages by giving them numbers, with the page with the smallest number being displayed first. The other method is to drag and drop the pages into the desired order.
3. Finally, click on the "Save organization" button.
