Meta Box Show Hide is an extension for the Meta Box plugin, which helps developers to show/hide meta boxes by page template, post format, category or custom taxonomy. This extension uses JavaScript to show/hide elements immediately and can combine conditions (include, exclude, logical operator AND, OR) to create as many restrictions as you want.

Developers  don’t need to rewrite any meta box definitions. Just add conditions for meta boxes for where to show or hide them, then other works will be done automatically. And no need to get stuck with writing custom PHP to check.
