Hi there.
I found that I cant disable the paramiter "Fetch items from children categories" during create menu as
Menu>K2>Categories.
I seek for solution and some articles tells it can disable in Catalogue mode.
But I cant find the way to get in Catalogue mode.
So how can can I get in Catalogue mode or how to disable "Fetch items from children categories"?
Thanks.

Hi. When you select only one category in the menu then the settings that are being applied are the category settings. Category settings can be edited in the category edit page. There you will find the "Catalog mode" which is equivalent with the menu link's "Fetch items from children categories" .

Thanks a lot! I found it already!

You are welcome.
