Hi,
We don't have yet a documentation for the new menus / modules settings, but it is in progress.
So to have a category listing menu displaying products too you just have to create a new menu with the type HikaShop > Categories listing, then in the tab "category option" select the layout, the desired category, and in the "product options" tab select the desired layout too, don't forget to set a number of row and columns in the first part of the options.
Then adapt the settings to your needs and job is done.
