You can add multiple categories and sub-categories in Catalog Bar.

Add a new category by clicking on the “+Add New Category” in Catalog Bar CMS, if you haven’t already added one.

You can add more categories as required. To create a sub- category, drag the category from the left button and drop it under another category as shown in the image below.

You can even create sub-categories within your sub-categories to create an n-level hierarchy of categories.
