Today I was looking for ways to make widget appear/ disappear on the sidebars of select pages. WordPress unfortunately does not have any facility to selectively control appearance of widget. DISPLAY WIDGETS is a very handy plugin which gives you complete control. You can download it from the link – http://wordpress.org/plugins/display-widgets/
Install it and go to the widgets section. Click on the widgets that you currently have installed and you will see some extra options as below.
The SHOW WIDGET for lets you control if the widget is to be displayed only to logged in users or all users.
The SHOW ON CHECKED PAGES lets you select pages, categories and posts on which you want them to appear.
The HIDE ON SELECTED PAGES let you select pages, categories and posts on which you want to hide them.
