hello expert
          gud day, may i ask if there is a treeview control that i can use here

There are two components in the Forge that should help you.  Just do a search for 'tree' and you'll find them.
Thanks Sir Curt..actually i'm just started today and following samples i found its good and its RAD question how can i put this treeview in my design?

I tried to use the Tree Widget but it is too old to perform on version 9
Mahinay - I would suggest learning all the basics first using the training videos before working on adding the Tree function.

Luciano - use the JsTree component - it was created with version 8 and should convert with no problem to version 9.
