  The template is expected to have a top-level element with the class
  'selectivity-multiple-selected-item'. This element is also required to have a 'data-item-id'
  attribute with the ID set to that passed through the options object.
  
  An element with the class 'selectivity-multiple-selected-item-remove' should be present
  which, when clicked, will cause the element to be removed.
  
  @param options Options object containing the following properties:
  highlighted - Boolean whether this item is currently highlighted.
