I want to dynamically set the selected item in a dropdowm list box. That is ,I have two drop down list boxes. with two items only viz. TRUE and FALSE for each one.
Now, once I select TRUE, then other must be automatically set two FALSE. and vice versa. That is no two boxes can have TRUE at the same time.
F F -> OK
F T -> OK
T F -> OK
T T -> ERROR, should be False.
