Once you add the widget to your sidebar from Appearance -> Widgets, you’ll see that the widget settings look like this:

Title – Sets the title that will display above the categories in the sidebar. (i.e. Categories)

Show as dropdown – Check this box to display the categories in a drop down menu rather than as a list. This is handy if you want to save space or have a lot of categories.

Show post counts – If this box is checked, the the total number of published posts for that particular category will be displayed next to the link. You can show post counts with both the list and dropdown menu formats.

Show hierarchy – If you have parent and child categories (subcategories within main categories) you can choose to display the hierarchy (pictured below) or just leave the list “flat,” without indicating which subcategories fit inside your main categories (pictured above). You can show category hierarchies with both the list and dropdown menu formats.
