flexible height

Hi, Moro,
The Mif.Tree is great! Thanks!

What libraries from 'Mootools download' are necessary. Don't know why I can use only library from your example. Otherwise, it doesn't work.

And how to do flexible height. I use styles

#tree_container { height:300px; width:300px; position:relative; }

And height is limited 300px

When I try something like

#tree_container { width:300px; overflow: auto; }

Tree is located over.
