UL menu php

Because my menu is not correctly working in IE8 and below i’m trying to add a static ul, li based menu. But im not a php pro and i dont know if its possible to make a basic menu with the UL class that will look like the normal menu but no accordion effect but only opens and basic css.

The code must be replaced at the echo test;.

I tried to find some information on how to display the main pages from the subpages. But i can’t find the correct code and i can’t get it to work with the ul code.

Let’s say i use the basic codee wp_list_pages(‘title_li=’); to view the menu. I can’t change the css for the main and submenu items this way.

This code works but still gives me a bad layout in IE8 and below:

wp_nav_menu(array(
              'menu' => 'main',
              'container_id' => 'iemenu',
            ));

<?php
function ae_detect_ie()
{
    if (isset($_SERVER['HTTP_USER_AGENT']) && (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== false))
        return true;
    else
        return false;
}

// Use the function and create a condition
if(preg_match('/msie [2-8]/i',$_SERVER['HTTP_USER_AGENT'])) {

   // if IE<=8

echo test;

}else{

      wp_nav_menu(array(
              'menu' => 'main',
              'container_id' => 'cssmenu',
              'walker' => new CSS_Menu_Maker_Walker()
            ));
}
?>
