Question about categories
 

Is there any mod or addon or way that allows you to make something like this.

Question 1:

Menu item: subjects
- When clicked shows a page full of categories with subjects, with a icon picture (this is what i don't know how to make) When you click on a categorie within it, then you get to see all the articles or pictures from that categorie

Menu item: Articles
- When clicked show a page full of categories with pictures, with a icon picture (this is what i don't know how to make) When you click on a categorie within it, then you get to see all the articles or pictures from that categorie

Cause problem i have now, i can make menu items, but when clicked they just show all the articles. I just want to add a categories page before showing the pictures, to make the articles more organised. I know there is the categorie menu, but that's not enough, because i have different types of articles, which should get there own categories in a page

I'm sorry if this sounds a stupid question, but I have honestly no idea where to even begin with this. I'm not so well experienced yet.

Any help would be realy appreciated!!

Question 2:

I'm sure this would be fairly easy, but i can't seem to make it work. Unregistered users can see the icon and preview text of the article, but they can't read the full article unless they register. Right now, i can hide the articles from unregistered users. But when i show the preview to guests, they can also read the full article, i wish i could prevent that.

Any tips realy realy welcome!

Thank you
