Catalog Bar gives you an option to directly display PDFs or documents against a category. The other default option is to simply add products in a category.
Select the category from Catalog Bar CMS and select the option “Open a document for this category” under the “Show products or a document” section.
Select your document from the Step 3 section by clicking on the box in front of Document. Select your file from the Media Library and hit “Save”.
Warning: If you’re converting a product category into a document category, you may lose all the products and information listed under that category
