Install custom sidebars in place of the current theme’s. Present pertinent information on your pages. Now, you can create a custom sidebar for one or more pages, templates, posts, custom post types, taxonomies, etc. (any combination) in place of an existing sidebar (widget area). Only the pages you choose will have the new sidebar’s content displayed in the exact same location as the one you choose to replace. To ensure that the content in the sidebar remains visible even when the user scrolls down the page, you can also easily make it sticky. Make a unique sidebar. Decide which sidebar needs to be changed. Select any collection of pages, templates, posts, custom post types, taxonomies, etc. to display the custom sidebar.
