Checking and unChecking group of menu items

Hi,

I have a group of menu items which I need to check and uncheck. There are a total of seven menu items and I only want one to be check at any one time.

Is there any easy way to do this or do I have to provide a handler to check each item when click and uncheck the rest of the menu items??

Thanks,
Steve Chia

I think you have to check manually your menu items. Sorry.
