How to create a static WordPress navigation menu

     
<?php 
 if ( is_page('Home') ) { $current = 'menu_one'; } 
  elseif ( is_page('Services') ) { $current = 'menu_two'; } 
  elseif ( is_page('Portfolio') ) { $current = 'menu_three'; } 
  elseif ( is_page('Tutorials') ) { $current = 'menu_four'; } 
  elseif ( is_page('About') ) { $current = 'menu_five'; } 
  elseif ( is_page('Contact') ) { $current = 'menu_six'; } 
?>

2. Add the html code below to the -body- part of header.php:

<div id="navbar">
    <ul id="nav" class="clearfloat">
        <li id="menu_one"><a href="index.php?page_id=15">Home</a></li>
        <li id="menu_two"><a href="index.php?page_id=7">Services</a></li>
        <li id="menu_three"><a href="/yourtheme/archives/category/Portfolio">Portfolio</a></li>
        <li id="menu_four"><a href="/yourtheme/archives/category/tutorials">Tutorials</a></li>
        <li id="menu_five"><a href="index.php?page_id=9">About</a></li>
        <li id="menu_six"><a href="index.php?page_id=13">Contact</a></li>
    </ul>
