I have made a Joomla menu as before - linked with one Joomla "core" category for each menu item.
Before that I made the K2 categories - with the same items - so entering the same words three times on different places. And linking them all together.
When I click on the menus on the frontend, huge folders appear - though not always. i was told to press "hide" under K2's Category View options - but that does not help at all.

I am now able to write articles in K2, but the appearance is no good.

So - how do I get out of this? These folders make my website look like an IT-site - distracting the attention from the content. Looking forward to comments how to deal with it.
