Are you after something like this:

<html>
<head>
<title>http://www.experts-exchange.com/Programming/Languages/Scripting/JavaScript/Q__26841139.html</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js" type="text/javascript"></script>
<script>

$(function() {

  $(".click-me")
  .click( eventClick )
  .css( { cursor: "hand" } );

});

function eventClick() {
  var id = $(this).attr( "rel" );
  if ( $("#"+id).length == 0 ) {
    $(this).after(
      $("<textarea/>").attr( { id: id } )
    );
  } else {
    $("#"+id).toggle();
  }
}

</script>
</head>
<body>

<ul>
  <li class="click-me" rel="1">Alpha</li>
  <li class="click-me" rel="2">Bravo</li>
