I am trying to generate a menu using wp_nav_menu. My expected output is this:

        <!-- Main Menu -->
<div class="navbar navbar-blue navbar-fixed-top" style="margin-top:74px">
    <div class="navbar-inner">
        <div class="container">


            <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </a>
            <div class="nav-collapse collapse">

                                <ul class="nav">
                    <li class="divider-vertical"></li>
                    <li class="dropdown dropdown-hover">
                        <a href="dashboard.html?lang=en" class="dropdown-toggle" data-toggle="dropdown">Dashboard <b class="caret"></b></a>
                        <!-- Dropdown Menu -->
                        <ul class="dropdown-menu">

</div>
<!-- End Main Menu -->

So far I am able to use a custom walker function to wp_nav_menu and achieved to generate almost all the html as above but I am unable to insert class="dropdown-toggle" data-toggle="dropdown" inside the tag. This will allow me to toggle the dropdown I guess (currently I am able to generate only the top menu. The submenu's appear in html but they are not visible in browser.).

Here is my effort so far:

        <!-- Main Menu -->
<div class="navbar navbar-blue navbar-fixed-top" style="margin-top:74px">
    <div class="navbar-inner">
        <div class="container">


            <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </a> 
<?php class My_Walker_Nav_Menu extends Walker_Nav_Menu {
function start_lvl(&$output, $depth) {
$indent = str_repeat("\t", $depth);
$output .= "\n$indent<ul class=\"dropdown-menu\">\n";
}
}
$defaults = array(
'theme_location'  => '',
'menu'            => '',
'container'       => 'div',
'container_class' => 'nav-collapse collapse',
'container_id'    => '',
'menu_class'      => 'nav',
'menu_id'         => '',
'echo'            => true,
'fallback_cb'     => 'wp_page_menu',
'before'          => '',
'after'           => '',
'link_before'     => '',
'link_after'      => '',
'items_wrap'      => '<ul id="%1$s" class="%2$s"><li class="divider-vertical"></li>%3$s</ul>',
'depth'           => 0,
'walker'          => new My_Walker_Nav_Menu
     );

     wp_nav_menu( $defaults );

      ?>
        </div>
    </div>

</div>
<!-- End Main Menu -->

Can somebody help me to modify my custom walker function so as to get the desired html output given above. Thanks in advance.

You want to modify the start_el method as you did the start_lvl one. At its most basic it would mean altering this line:

$item_output .= '<a'. $attributes .'>';

To look like this one:

$item_output .= '<a class="dropdown-toggle" data-toggle="dropdown"'. $attributes .'>';

It looks like you will need more complicated logic to avoid inserting that string in all the submenus, but that is the idea.

Thanks for reply. I've just tried this code: [link]gist.github.com/1817371 and its working well. I had to tweak it minorly to make my sub-menus appear. –  Wordpress Kid Jan 13 '13 at 4:51
