  I think you use jquery to that just put this code in the footer
  
  
  <script language='javascript'>
  $('.menu li').removeAttr('id');
  </script>

    Hi, I don't want a jQuery solution if it's possible to do this with a Walker. The problem isn't removing the ID's, but removing the classes + keeping the active's working.

  Hello,
  
  There are filters provided for these attributes so you can get away without a separate walker. You could easily remove the id and all of the classes with this code snippet:
  

  
  
  // filter the id and class attributes of nav menu items
  
  add_filter( 'nav_menu_item_id', 'filter_nav_menu_attributes' );
  
  add_filter( 'nav_menu_item_id', 'filter_nav_menu_attributes' );
  
  
  
  // function that returns false
  
  function filter_nav_menu_attributes($content) {
  
  
  
  	return false;
  
  
  
  }
  
  

  
  
  It is possible to filter the classes separately and leave the necessary ones, but it requires some more advanced PHP magic. I'll try to see if I can manage to hack it.

    Hi,
    
    Sounds good! The filters are great, if you can manage to keep the current states in this filter it would be a perfect solution.

    Well, this is where I got so far:
    

    
    
    function filter_nav_menu_id( $id ) {
    
    
    
    	return false;
    
    
    
    }
    
    
    
    function filter_nav_menu_classes( $classes ) {
    
    
    
    	// create array for new classes
    
    	$new_classes = array();
    
    	
    
    	// perform regex match for certain strings and merge the new arrays
    
    	$new_classes = preg_grep( '/current-menu-item/', $classes );	
    
    	$new_classes = array_merge( $new_classes, preg_grep( '/current-menu-parent/', $classes ) );
    
    	$new_classes = array_merge( $new_classes, preg_grep( '/current-menu-ancestor/', $classes ) );
    
    	
    
    	// return the new array with classes
    
    	return $new_classes;
    
    
    
    }
    
    
    
    add_filter( 'nav_menu_item_id', 'filter_nav_menu_id' );
    
    add_filter( 'nav_menu_css_class', 'filter_nav_menu_classes' );
    
    

    
    
    The only drawback here is that an empty class attribute remains on the menu items. Unfortunately there's no filter for that so the only way to remove it would be to use a custom walker that is just a slightly modified version(just a single line) of the default one. Something like that works:

    Cheers!

    An improved version of the walker + classes filter:
    http://pastebin.com/BVgnrjx5
    
    This version uses a little less code. I've removed from the walker the part that builds the id attribute (and because of that the id filtering function is no longer necessary).
