    <label for="c1">Menu1</label>
  </li>
  <li>
    <input id="c2" type="checkbox">
    <label for="c2">Menu2</label>
  </li>
  <li>
    <input id="c3" type="checkbox">
    <label for="c3">Menu3</label>
  </li>
  <li>
    <input id="c4" type="checkbox">
    <label for="c4">Menu4</label>
  </li>

  </li>
  <li>
    <input id="c6" type="checkbox">
    <label for="c6">Menu6</label>
  </li>
  <li>
    <input id="c7" type="checkbox">

   step: function(now) {
    $(li)
      .css({ transform: 'rotate('+now+'deg)' })
      .find('label')
       .css({ transform: 'rotate('+(-now)+'deg)' });
   }, duration: 0
  });
}

// show / hide the options
function toggleOptions(s) {
  $(s).toggleClass('open');
  var li = $(s).find('li');
  var deg = $(s).hasClass('half') ? 180/(li.length-1) : 360/li.length;
  for(var i=0; i<li.length; i++) {
   var d = $(s).hasClass('half') ? (i*deg)-90 : i*deg;
   $(s).hasClass('open') ? rotate(li[i],d) : rotate(li[i],angleStart);
