Hello, I'm very new to k2 (but old in joomla), and I have a question... I searched in parameters but I don't find anything.

The site I am refering is this www.marimation.gr
I have some images, created as items in k2.
And I have created the category "portfolio" and the subcategories "illustrations", "characters", "posters" etc.

Here is my problem.
If I have the parameter of the portfolio categorie to show 5 items, I will have pagination, with some pages.
So when I click on portfolio I see the 5 first items of the catefory portfolio. But when I click on illustrations, I don't see the illustrations from the subcategory, but the items that are on the illustration category AND are on page1 of portfolio.

So what I want is, when I click on portfolio to see the last 5-10 items, but when I click on the subcategory, to see the items there even if they are not the one in the portfolio menu I clicked first.

Can anyone help me in this ?

(The only solution I can think, is to disable the subcategory blocks, and make submenu outside k2.But because there is no drop-down menu, it's not looking good at all...)
