Pages - Using PageMash to Organize Pages
The pageMash tool under Pages allows you to easily see a full list of your website’s pages and their hierarchy, as well as offering drag-and-drop functionality for ordering your pages. For some users this is a more intuitive way of looking at their website’s content:
Pages and sub-pages are “threaded,” such that you can click on a page’s icon to minimize a group of its sub-pages for a simplified list.
Each page in the list has a small arrow to the right; hover over it to see options for editing or deleting the page.
You can also drag and drop the page titles to rearrange them.
You must hit the Update button at the bottom right to finalize your changes or they will be lost.
