link blog-content section does not show categories

[sitronella]

Hello everyone
i have a recipe site (in Greek) and i am using Mambo 4.5.2
Besides the recipes, i have also some articles (tip-offs). I have made a section called tip-offs, with some categories (about sweets, main course, about the kitchen, general advice etc.)
I want to make a link in my topmenu, that will get me to the section of the tip-offs, but that will display the categories as blog. I have tried to make a link using " Blog - Content Section", but when one clicks there, it displays all the articles and not a list of the categories.
Can anyone help me here?
The site is in Greek so i will give you a link, but i don't know how helpful this will be.

if you go to the top menu and click on the "Συμβουλές" button, it takes you to the tip-offs. Right now it displays all articles. But since they are growing more and more, i want to categorize them.
So, as I said, i want it to have exactly the same look, but instead of the articles, to show the categories. Can it be done?
