Include this function on your page:

function toggle(target) {
            obj=(document.all) ? document.all[target] : document.getElementById(target);
            obj.style.display = (obj.style.display == 'block') ? 'none' : 'block';
      }

Then use the following code for each checkbox (just change the stuff all in caps):

<input type="checkbox" name="NAME" onclick="toggle('DIV_ID')" />

And of course set display:none; for each of the elements so that they start of hidden. Then when the user clicks on the checkbox to check it, the element will appear.

Of course you have to wrap that function in script tags and it should go in your head tag:

<script type="text/javascript">
function toggle(target) {
          obj=(document.all) ? document.all[target] : document.getElementById(target);
          obj.style.display = (obj.style.display == 'block') ? 'none' : 'block';
     }
</script>
