List articles from a category in a horizontal dropdown menu

Hello guys!

I’m a quite rookie WordPress user, and I’ve got a question what I can not solve.

I have a website with a built in horizontal menu. I can add dropdown categories in there. When I point on it the list of sub categories appear. When I click on a sub category the related articles are listed.

What I want to do is to display the articles in the drop down menu, so when I click on the title of the article the post appears.

Are there any solution to do this?

Here is my navigation code:

<!-- NAVIGATION  -->
        <div id="navbar">
                <ul id="navcatlist">
                        <li<?php if(is_home() ) { ?> class="current-cat"<?php } ?>><a href="<?php bloginfo('url'); ?>" title="<?php bloginfo('description'); ?>"><?php echo $blognews["home"]; ?></a></li>
                        <?php if ($bnews_options['enBlog'] == 1)
                                {
                                        wp_list_categories('orderby='.$bnews_options["orderBy"].'&order='.$bnews_options["order"].'&child_of='.$bnews_options["blogID"].'&title_li=&depth=2&exclude='.$bnews_options["excludeCategories"]);
                                }
                                else
                                {
                                        wp_list_categories('orderby='.$bnews_options["orderBy"].'&order='.$bnews_options["order"].'&title_li=&depth=2&exclude='.$bnews_options["excludeCategories"]);
                                }
                        ?>
                </ul>
        </div><div class="clear"></div>
        <!-- END OF NAVIGATION  -->

I have already found something which almost does what I want to do, but It is not exactly what I need because this code lists the articles from a category but not in a drop down menu format, but only next to the other menus. Every article a new menu in this case. Is it possible to integrate the two codes somehow in order to appear in a drop down format?

<ul>
<?php
global $post;
$myposts = get_posts('numberposts=5&category=1');
foreach($myposts as $post) :
?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endforeach; ?>
</ul>

Can it be solved somehow?

Thank you very much the information in advance!
