JQuery Control Plugin Treeview

JQuery Control Plugin Treeview

Hello:
 
I have an MVC page that contains Treeview in JQuery. There are two panes and the treeview reflects information on the right pane.
I am trying to put a dropdown on page top, such that an item selected on the left pane, displays some of the informaiton in the dropdown, using JQuery.
 
Any suggestions for this ?
