We'll create fresh WordPress site with Widget Display Options installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Widget Display Options adds fields to all registered widgets that allow you to contextually hide or show any widget based on a set of chosen conditions. Many of the conditions accept parameters so you could, for example, only show a widget on the single view of a given page or post, or hide it on the archive pages of a given post type or category, etc.
Additionally this plugin provides an input field to add custom classes to the widget wrappers.
Available Conditions:
Items marked with an * accept parameters.
