i used this to get things done:
<div id="navigation">
<ul id="menu" class="menu">
<?php wp_list_pages('depth=1&sort_column=menu_order&title_li='); ?>
</ul>
</div>
<div id="subnavigation">
<?php
if($post->post_parent)
$children = wp_list_pages("title_li=&sort_column=menu_order&child_of=".$post->post_parent."&echo=0"); else
$children = wp_list_pages("title_li=&sort_column=menu_order&child_of=".$post->ID."&echo=0");
if ($children) {??>
<ul id="submenu" class="submenu"><?php echo $children;??></ul>
<?php }??>
</div>
you’ll need to style it so it will be horizontal, and not vertical.
this is the part in the stylesheet i needed:
#navigation {position: absolute; left: 0px; top: 36px; width: 820px; height: 36px; background: url('img/transparenz.png');}
#subnavigation {position: absolute; left: 0px; top: 72px; width: 820px; height: 26px; background-color: #FFFFFF;}
ul#menu {margin:0px; list-style-type: none; height:35px; margin-top: 10px;}
ul#menu li {float:left; margin: 0px; padding-right: 28px;}
ul#menu li a, a:visited {color: black; text-decoration: none;}
ul#menu li a:hover {color: #8f0f26;}
ul#submenu {margin:0px; list-style-type: none; height:35px; margin-top: 5px;}
ul#submenu li {float:left; margin: 0px; padding-right: 35px;}
ul#submenu li a, a:visited {color: black; text-decoration: none;}
ul#submenu li a:hover {color: #8f0f26;}
.current_page_item {font-weight: bold; color: #8f0f26;}
put it either in the header.php or in your index.php … depending on how you set up your template.
