Hello, i am a new to the K2 community,
I would like to have some help for K2 in the view options of the item.

I cannt find the "fields" that i are managing the Item View options example: showing or not the "related items", "Rate this item".... or Hide the item toolbar ...and all the others
I have the joomla 3 platform.

Thanks in advance!

All the options you need to edit are located under the category settings.
