   I want to make these menu, by using wp_nav_menu() and custom walker which I found in the internet. Please, help my to modify walker and wp_nav_menu() to get this ul structure:

   <ul class="nav">
                 <li class="dropdown"><a href="#" class="dropdown-toggle" data-toggle="dropdown">111<b class="caret"></b></a>
                   <ul class="dropdown-menu">
                     <li><a href="">333</a></li>
                   </ul>
                 </li>
                 <li class="dropdown"><a href="#" class="dropdown-toggle" data-toggle="dropdown">222<b class="caret"></b></a>
                   <ul class="dropdown-menu">
                     <li><a href="">222.1</a></li>
                     <li><a href="">222.2</a></li>
                   </ul>
               </ul>

   <div class="tabbable tabs-left">
               <?php  wp_nav_menu( array('menu_class' => 'nav',
                                       'container' => false,
                                       'container_class' => 'main-menu-container',
                                       'theme_location' => 'header-menu1',
                                       'walker'=> new header_Walker_Nav_Menu()
                                       ) ); ?>
             </div>

   class header_Walker_Nav_Menu extends Walker_Nav_Menu {
   	/**
   	 * @see Walker::start_el()

   	function start_el(&$output, $item, $depth, $args) {
   		global $wp_query;           
   
   		$indent = ( $depth ) ? str_repeat( "\t", $depth ) : '';
   
   		$class_names = $value = '';
   
   		$classes = empty( $item->classes ) ? array() : (array) $item->classes;
   		$classes[] = 'menu-item-' . $item->ID;
   
   		$class_names = join( ' ', apply_filters( 'nav_menu_css_class', array_filter( $classes ), $item, $args ) );
   		$class_names = ' class="' . esc_attr( $class_names ) . '"';

   		$attributes  = ! empty( $item->attr_title ) ? ' title="'  . esc_attr( $item->attr_title ) .'"' : '';
   		$attributes .= ! empty( $item->target )     ? ' target="' . esc_attr( $item->target     ) .'"' : '';
   		$attributes .= ! empty( $item->xfn )        ? ' rel="'    . esc_attr( $item->xfn        ) .'"' : '';
   		$attributes .= ! empty( $item->url )        ? ' href="'   . esc_attr( $item->url        ) .'"' : '';
   
                   // new addition for active class on the a tag
                   if(in_array('current-menu-item', $classes)) {
                       $attributes .= ' class="active"';
                   }
   
   		$item_output = $args->before;
   		$item_output .= '<a class="dropdown-toggle" data-toggle="dropdown"'. $attributes .'>';
   		$item_output .= $args->link_before . apply_filters( 'the_title', $item->title, $item->ID ) . $args->link_after;
   		$item_output .= '</a>';
   		$item_output .= $args->after;
   
   		$output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );
   	}
   }

   - how to change

   for sub-menu elements?
   - how to make different <li class="drop-down"> and
   • for different menu levels?
     - How to delee id'd and excess classes? f.e: <ul id="menu-header-menu">, <li id="menu-item-122" class="menu-item menu-item-type-custom menu-item-object-custom current-menu-item current_page_item menu-item-home menu-item-122">
