How do I add a parameter to category K2 back-end?

Question

I need to add a parameter to category in K2 back-end in order to use it in a view. I've tried to add one: to components\com_k2\views\itemlist\tmpl\category.xml and administrator\components\com_k2\models\category.xml

but I still can't see the parameter in a category in K2 back-end.

How can I add a parameter?

Thanks for advance!

Answer 1

k2 has the option to add extra fields.

Create an extra fields group and then add some fields to it and assign it to some categories.
