  You will probably need to tell the editor where to find its 'add' and 'delete' images.  In your
  code, before you make the editor, do something like this:
     JSONEditor.prototype.ADD_IMG = '/javascripts/jsoneditor/add.png';
     JSONEditor.prototype.DELETE_IMG = '/javascripts/jsoneditor/delete.png';

  You can enable or disable visual truncation in the structure editor with the following:
    myEditor.doTruncation(false);
    myEditor.doTruncation(true); // The default

  You can show a 'w'ipe button that does a more aggressive delete by calling showWipe(true|false) or by passing in 'showWipe: true'.
