If one service from a package is selected the other package services shouldn't be selected.I have 6 other packages User should be able to select one at a time from these different sets of packages please help.

Answer 1

Since the name is the same, I bind event handler on input and name.

I don't know whether you use jQuery or not.

For convenience I did it below by jQuery.

Only thing I did is to add the event handler.

$('input[name="service"]').click(function(event){
   $('input[name="service"]:checked').not(this).prop('checked', false);
})
