There are two ways you can do that.

  1. Create 2 separate TPopupMenu objects with the desired menu items, do not assign either one of them to the TreeView's PopupMenu property, and then use the TreeView's OnContextMenu event to call the Popup() method of whichever TPopupMenu you need based on which node the user is clicking on.

  2. Create 1 TPopupMenu object and put both menu items in it, and assign it to the TreeView's PopupMenu property, then use the TPopupMenu.OnPopup event to show/hide the menu items based on which node the user is clicking on.

In either case, you can use the TTreeView.GetNodeAt() method to determine which node is located at the coordinates of a mouse click, if any.
