i've created with my friend that code 

<div class="ordered">
            <ul>
                <?php
                $db = JFactory::getDBO();
                $query = 'SELECT count(*) as nm, SUBSTR(title,1,1) as alpha FROM #__content WHERE catid = '.$catid.' GROUP BY SUBSTR(title,1,1)';
                $db->setQuery($query);
                $mostIng = $db->loadObjectList();
                foreach ($mostIng as $row) {
                    echo '<li data-text="'.$row->alpha.'">'.$row->alpha.' '.'</li>';
                }
                ?>
            </ul>
        </div>
