fobid some of the choices of a Radio Button

[alii001]

      I am using the Radio Button to choose orders, when some(not all) of the orders are not available , I need to make those choices unreachable, such as make the button unvisiable or make it can not be clicked or grayed , what shall I do ? 

      thanks!

This picture should explain it:

You can also do some googling, there are videos showing how to disable or hide controls in LabVIEW.
