Widgetize is a WordPress plugin that allows any page or post to be fully or partially widgetized. Widget areas can be added above or below page content, or replace page content entirely.

For a limited time only, purchase an unlimited license to use Widgetize on as many sites as you’d like for the lifetime of the product along with free updates. At the end of the month, this will change to a yearly license.
