    Hi all,

    I was wondering if some one could help me with this.

    I was trying to add the attribute data-role="none" to the

      class="sub-menu" using Walker Class. However im stuck.

      here is my html output...

      <li id="menu-item-132" class="menu-item menu-item-type-post_type menu-item-object-page current-menu-item page_item page-item-21 current_page_item menu-item-has-children menu-item-132">About
      <ul class="sub-menu" style="display: block;">

    and here is my custom walker class

    class my_nav_walker extends Walker {
    var $tree_type = array( 'post_type', 'taxonomy', 'custom' );
    var $db_fields = array( 'parent' => 'menu_item_parent', 'id' => 'db_id' );
    function start_lvl( &$output, $depth = 0, $args = array() ) {
    $indent = str_repeat("\t", $depth);
    $output .= "\n$indent<ul class=\"sub-menu\">\n";
    }

    function end_lvl( &$output, $depth = 0, $args = array() ) {
    $indent = str_repeat("\t", $depth);
    $output .= "$indent\n";
    }

    function start_el( &$output, $item, $depth = 0, $args = array(), $id = 0 ) {
    $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_names ? ' class="' . esc_attr( $class_names ) . '"' : '';
    $id = apply_filters( 'nav_menu_item_id', 'menu-item-'. $item->ID, $item, $args );
    $id = $id ? ' id="' . esc_attr( $id ) . '"' : '';
    $output .= $indent . '<li' . $id . $value . $class_names .'>';
    $atts = array();
    $atts['title'] = ! empty( $item->attr_title ) ? $item->attr_title : '';
    $atts['target'] = ! empty( $item->target ) ? $item->target : '';
    $atts['rel'] = ! empty( $item->xfn ) ? $item->xfn : '';
    $atts['href'] = ! empty( $item->url ) ? $item->url : '';
    $atts = apply_filters( 'nav_menu_link_attributes', $atts, $item, $args );
    $attributes = '';
    foreach ( $atts as $attr => $value ) {
    if ( ! empty( $value ) ) {
    $value = ( 'href' === $attr ) ? esc_url( $value ) : esc_attr( $value );
    $attributes .= ' ' . $attr . '="' . $value . '"';
    }
    }
    $item_output = $args->before;
    $item_output .= '<a'. $attributes .' data-role="none">';
    $item_output .= $args->link_before . apply_filters( 'the_title', $item->title, $item->ID ) . $args->link_after;
    $item_output .= '';
    $item_output .= $args->after;
    $output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );
    }
    function end_el( &$output, $item, $depth = 0, $args = array() ) {
    $output .= "\n";
    }
    }

    ?>

    any help is appriciated
