Так я привёл весь код, задействованный в работе. Ну а если нужен полный полный пример, то вот:

<?php
defined('_JEXEC') or die('Restricted access');
$doc = & JFactory::getDocument();
$doc->addStyleSheet('components/com_catalog/files/css/main.css');
$doc->addScript('components/com_catalog/files/js/jquery-1.7.min.js');
?>
<script>
    $(document).ready(function(){
        tools();
        
        $('a.add').hover(
            function(){$(this).find('div').stop().animate({opacity: '1'}, 200);}, 
            function(){$(this).find('div').stop().animate({opacity: '0'}, 200);}
        );
        
        $(':checkbox[name=category]').click(function(){
            if($(this).is(':checked')) {
                $(this).parent().parent().find('ul li input:checkbox[name=subcategory]').attr('checked', 'checked').attr('disabled', 'disabled');
            } else {
                $(this).parent().parent().find('ul li input:checkbox[name=subcategory]').removeAttr('checked').removeAttr('disabled');
            }
            tools();
        });
        
        $(':checkbox[name=subcategory]').click(function(){
            tools();
        });
        
        function tools() {
            var numCategory = $(':checkbox[name=category]:checked').length;
            var numSubCategory = $(':checkbox[name=subcategory]:checked').length;
            if(numCategory > 0 || numSubCategory > 0) {
                $('.fixBlock.tools').fadeTo('200', 1).find('input:button').removeAttr('disabled');
            } else {
                $('.fixBlock.tools').fadeTo('400', 0.2).find('input:button').attr('disabled', 'disabled');
            }
        }
        
        $('.fixBlock.edit input:button').attr('disabled', 'disabled');
        $('.fixBlock.edit textarea').attr('disabled', 'disabled');
        $('span.editTitle').click(function(){
            $('.fixBlock.edit').fadeTo('200', 1).find('input:button').removeAttr('disabled').parent().find('textarea').removeAttr('disabled');
            $('.fixBlock.edit textarea').text($(this).text());
            $('.fixBlock.edit input[name=editId]').val($(this).parent().find('input:checkbox').attr('value'));
        });
        $('.fixBlock.edit :button[name=cancelEdit]').click(function(){
            $('.fixBlock.edit').fadeTo('400', 0.2);
            $('.fixBlock.edit textarea').empty().attr('disabled', 'disabled');
            $('.fixBlock.edit input[name=editId]').val('');
            $('.fixBlock.edit input:button').attr('disabled', 'disabled');
        });
        
    });
</script>

<form method="post" action="index.php">
    <div class="comWrapper comTable">
        <?php
        $cellInRow = '0';
        foreach($this->data as $group) {
        ?>
        <?php echo ($cellInRow == '0') ? '<div class="comTableRow">' : ''; ?>
        <div class="comTableCell">

                </div>
                <?php echo $this->model->subcategory($group->subcategory); ?>
            </div>
        </div>
        <?php
        $cellInRow++;
        if($cellInRow == '3') {echo '</div>'; $cellInRow = '0';}

    </div>
    
    
</form>

Только это слой с вида (компонент для Joomla)
