[CLOSED] Build a tree.. How?

[opendat2000]

I want to build a Tree with the data getting from the database. The tree must be dynamical, because that can have different levels.


Example:

1.- Select from a Combobox some data.
2.- Use the Value from the data selected to search and retrieve another data from the database.
3.- Load the data in a treepanel and automaticly build the tree

Like I mentioned, the tree can have different levels, it depend for the data selected. (Ex. The data can have, three levels, or four levels, or five, etc).


So, how I can do that? I see examples, and search in the internet, but I can't find that I need.

Thanks a lot, Best Regards.
