Here's the tree structure of a Level 1 site in AT Internet:
- Level 1 site
- Level 2 site
- Chapter 1
- Chapter 2
- Chapter 3
- Page
- Chapter 3
- Chapter 2
- Chapter 1
- Level 2 site
You have up to 5 levels of classification within a Level 1 site.
The page being the mandatory element, it is always the last level of the tree structure. You are free to sort a page into chapters (up to 3 levels).
If this is not enough, you can also use other features such as Custom Site Variables or Custom Tree Structure.
