The custom sidebar post type is created to allow users to register additional sidebars. By default, our themes have a few sidebars for pages, blog, shop, single product, shop filters, and footer. But there is an ability to specify different sidebars for each particular post, product, or page. Here is a step by step instruction:
- Go Dashboard -> Sidebars -> Add new
- Name your custom sidebar and save it
- Go to Appearance -> Widgets and fill your sidebar with any widgets you need
- Edit any page, post, or product and specify the newly created sidebar.
