title: How can I make a group of checkboxes mutually exclusive?
body: <p>I have to make mutually exculsive checkboxes.  I have come across numerous examples that do it giving example of one checkbox group.
  One example is at <a href="http://blog.schuager.com/2008/09/mutually-exclusive-checkboxes-with.html" rel="noreferrer">http://blog.schuager.com/2008/09/mutually-exclusive-checkboxes-with.html</a>.</p>
  
  <p>In my case, I have many checkbox groups on the same page, so I want it to work like <a href="http://student.zwebinfo.net/mmosby/project/mutexCheckbox.aspx" rel="noreferrer">this example</a>.
  An asp.net codebehind <a href="https://stackoverflow.com/questions/7749960/make-two-checkbox-lists-mutually-exclusive">example is here</a>, but I want to do it in client side code.</p>
  
  <p>How can I do this in JavaScript?</p>
  
  <p>i have decided to use the ajax mutually exclusive checkbox extender. 
  The solutions given so far are basically based on radio buttons.
