title: More than one selector for context menu
body: <p>How can I have two different context menus against different elements? I tried this but though I don't get errors, it doesn't work:</p>
  
  <pre><code>$(function(){
    $.contextMenu({
      selector: '.dragIndiv, .dragGroup', 
      autoHide: 'true',
      callback: function(key, options) {
        // do something
      },
      items: {
        "amend"   : {name: "Amend", icon: "amend"},
        "relate"  : {name: "Relate", icon: "relate"}
      },
      selector: '#elementPallet', 
      autoHide: 'true',
      callback: function(key, options) {
        // do something else
      },
      items: {
        "submit" : {name: "Submit", icon: "aligntop"},
        "viewSource": {name: "View source", icon: "alignleft"},
      }
    });
  });
  </code></pre>
