How To Install & Use PageMash For WordPress by newbizblogger
PageMash makes menu manipulation easy. Use if if you want to hide pages so they don’t show up on your menu, or if you want to quickly rename the page, or if you want to create parent/child pages (an odd way of saying “I want this page to appear as a dropdown on my menu”–the way the tutorials on The Open Road appear under “Useful Tools”). You could do all these things before, of course, but this makes it easy and intuitive in ways that new WordPress users will love. The above tutorial is just about perfect, and so we won’t try to improve upon it. Just note, however, that it won’t affect custom menus (though these have their own, relatively similar drag-and-drop interface.).
