I like to show data of 5 tables in a treeview. Is there an example of how to use the class Xoopstree or are there other possibilities to realize my idea?

My table structure:
--------------
TABLE: fields (PK = primary key, FK = foreign key)
1) FUNCTION: fu_id (PK), fu_name
2) CATEGORY: ca_id (PK), ca_name, ca_inuse, fu_id (FK)
3) SUBCATEGORY: sc_id (PK), sc_name, sc_inuse, ca_id (FK)
4) ITEM: it_id (PK), it_name, it_inuse, sc_id (FK)
5) RESULT: ir_id (PK), ir_name, it_id (FK)

Any suggestions?

Are there really no suggestions by anybody?

I assume you would like 5 pull select boxes of which the options depend on the selected value in another select box.

This will be possible with the help of javascript but it is definitely not easy .

Have a look at:
google newsgroup topic

and

Tecnorama (used this myself and it works great with dreamweaver)
