For custom sidebars per page, per post, per category, or anything in between, we recommend the WordPress plugin WooSidebars from WooThemes (the makers of WooCommerce): http://www.woothemes.com/woosidebars/.
- You can add one by going to Appearance → Widgets Area → Add New. In the Conditions area, you’ll see a menu that allows you to select the page where the new sidebar will be displayed. View the screenshot for details.
- After the new Widget Area was created and the page was selected, go to that page and set the Right Sidebar Page template from the Page Attributes section.
- The final step is to go to Appearance → Customize → Widgets and select the Custom Widget Area where you’d like to add your widgets.
