In this site there are three different tree formats.

·        Descendant Tree

·        Outline Tree

·        Dynamic Tree

The Descendant Tree has a classical family tree form of boxes connected by lines:

The Descendant Tree is the most conventional display, but it takes a lot of screen space.

The Outline is a list in which each row corresponds to an individual and each generation has a different indent:

The numbers in each row are the generation numbers. Outline is more space-efficient.

The Dynamic Tree is similar to Outline, but each family branch can be collapsed and opened, like folders in Microsoft Windows Explorer:

 Dynamic Tree gives you the possibility to decide how to navigate in the tree.
