HTML

<input type="checkbox" id="test" /> Check me

<div id="items"></div>

JavaScript

$("#test").bind('click', function() {

  var $t = $(this);

    if ($t.is(':checked')) {
    // append item
    $('#items').append('<span>I was recently appended.</span>');
  }else{
    // empty div and remove it from DOM (empty helps with memory leak issues with $.fn.remove() )
    $('span', '#items').empty().remove();
  }
});
