If additional text will page description (set in page setting) you have to modifity your nav_YOURNAME.tpl file.
It should lokks something like this:
Code:
<ul>
<?php foreach ($this->items as $item): ?>
<?php if ($item['isActive']): ?>
<li class="active"><a href="<?php echo $item['href']; ?>" title="<?php echo $item['pageTitle'] ? $item['pageTitle'] : $item['title']; ?>"<?php if ($item['class']): ?> class="<?php echo $item['class']; ?>"<?php endif; ?><?php if ($item['accesskey'] != ''): ?> accesskey="<?php echo $item['accesskey']; ?>"<?php endif; ?><?php if ($item['tabindex']): ?> tabindex="<?php echo $item['tabindex']; ?>"<?php endif; ?><?php if ($item['nofollow']): ?> rel="nofollow"<?php endif; ?> onclick="this.blur();<?php echo $item['target']; ?>"><?php echo $item['link']; ?>
<span><?php echo $item['description']; ?></span></a><?php echo $item['subitems']; ?>
<?php else: ?>[*]<a href="<?php echo $item['href']; ?>" title="<?php echo $item['pageTitle'] ? $item['pageTitle'] : $item['title']; ?>"<?php if ($item['class']): ?> class="<?php echo $item['class']; ?>"<?php endif; ?><?php if ($item['accesskey'] != ''): ?> accesskey="<?php echo $item['accesskey']; ?>"<?php endif; ?><?php if ($item['tabindex']): ?> tabindex="<?php echo $item['tabindex']; ?>"<?php endif; ?><?php if ($item['nofollow']): ?> rel="nofollow"<?php endif; ?> onclick="this.blur();<?php echo $item['target']; ?>"><?php echo $item['link']; ?>
<span><?php echo $item['description']; ?></span></a><?php echo $item['subitems']; ?>
<?php endif; ?>
<?php endforeach; ?>[/list]
for you most important is this piece:
Code:
<span><?php echo $item['description']; ?></span>
In other case when additional text is custom text only way is to use javascript.
