This module get the actual categories to display a list of related items for category
First, get the Menu value, if this is a K2 Categories get the categories params Second, if use a module like K2 Tools get the category for the link Thirt, if are in a Item view get the id of the item and get the category
Recently, I noticed that K2 wouldn't fetch menu item for items in a category that is not a direct parent of it. For example: I have My Article which is in the category B, which is a a descendant of the root category A. I created a K2 Categories menu item which uses A as the category. If I viewed My Article by clicking a link from the website I wouldn't retrieve a Menu Item.
The reason it's happening After digging into the K2's routing system, I noticed it doesn't allow for category ancestors routing. In our case, this means that even though My Article is in a category which is a descendant of A, you still wouldn't get a Menu Item for that, you must have created a specific menu item that uses B.
The fix In simple words, the fix is to add support for category ancestors routing. In technical words I have modified two core files of K2 in order to achieve this kind of routing behaviour, therefore if you use this fix you should be careful about it. I have attached the two files with this message.
Sj Mega K2 Items II supports for K2 Component which allows you to show items with categories on the frontpage as table. For normal items, you can see the image and the description via tooltip. Also, you can close categories which you are not interested.
