Hi if i click on the menu item the same item(with same name) in the treeview will be expanded and the other items will be collapsed this is working fine

but if i give the navigatr url to menu item it's not working

plss i want the code such that if i click on menuitem it should go to the corresponding page and the corresponding treeview itme should be expanded.
