Ed Nailor presented at WordCamp Raleigh 2012 about creating dynamic sidebars in WordPress. He discussed using plugins like Widget Logic to conditionally display widgets, but noted these had limitations for larger sites where managing multiple widgets across many pages would be difficult. Nailor then introduced his solution, a plugin called Truly Dynamic Sidebars, which allows scaling widget management to large sites by making sidebars fully dynamic and configurable without advanced technical knowledge. The plugin allows adding sidebars and assigning widgets to pages from the admin interface.
