Hi,

I want to create a tree menu from a list of values that comes something this:
...
CDs
Books|Adventure
Movies|Music
Books
Books|Sports
Movies
Movies|Adventure
Books|Drama
CDs|Classic
...

[download]

-There can be maximum 5 levels for now. If it's possible to make an entirely dynamic solution that would be great, but it's not necessary.

- As you can see, the category names may be used in several positions, but every row comes with a row of matching unique id:s, so Books|Drama will have for example 2|10. "Drama" can be used in several places and levels, and will always have the number 10 assigned, but there can also be another "Drama" category with another id. So I guess that the id is the key here (i.e. every id can have any name)

Basically, I need to create the tree structure based on the ids, with the names as a property of the id.
I don't have a good way of illustrating of how I want it to be, but I hope you get the idea...I hope you understand what I'm writing, am a bit tired:-)
