I am using K2 component to showcase my products. I have created a menu item in my main menu for showing all my product categories (without sub categories) in a catalog style (To do this I went to- menu item> K2>Item Listing>Categories). I have created three product categories and six product items, but when I click on the menu I created it just shows only one category and its items.

I want to display all the categories in a catalog style (But No sub categories or items) when clicked on the menu. For example: demo.getk2.org/en/catalog

Would you please kindly tell me how to do this?

Thanks in Advance
