WordPress Menu & Walker for ZURB's Foundation 4 Top Bar

Adding a Foundation Top Bar to WordPress

foundation-topbar-menu.php and foundation-topbar-walker.php should be required in the WordPress functions.php file.

The code in foundation-topbar.php should be added below the body tag in header.php

Setup a menu in WordPress admin under Appearance > Menus

Use the 'label' class on a menu item to create a menu section title

Can anyone point to a functioning starter theme that incorporates this? It would be very helpful to see exactly how this is implemented within the various files. Especially for us beginners. Thanks.

Excellent!

For the search form, or anything at the end of the menu I used this code:

add_filter( 'wp_nav_menu_items', 'your_custom_menu_item', 10, 2 );
function your_custom_menu_item ( $items, $args ) {
    if ($args->theme_location == 'top-bar-r') {
        $items .= '<li class="has-form">';
        $items .= '    <form role="search" class="searchform" method="get" action="' . home_url() . '">';
        $items .= '        <div>';
        $items .= '            <input id="sf-s" name="s" value="' . get_search_query() . '" type="text" onkeyup="buttonUp()" placeholder="Search..." />';
        $items .= '            <input id="sf-searchsubmit" type="submit" value="" />';
        $items .= '            <span class="search-icon-toggle" title="Click to Search"></span>';
        $items .= '        </div>';
        $items .= '    </form>';
        $items .= '</li>';
    }
    return $items;
}

(Obviously use whatever HTML you need)

I'm trying to add the description

if ( !empty( $item->description ) ) {
    $item_html .= '<span class="description">' . esc_attr( $item->description ) . '</span>';
}

But I'm unsure of where to place it amongst all this:

/ CUSTOMIZE THE OUTPUT OF MENUS FOR FOUNDATION TOP BAR 
class top_bar_walker extends Walker_Nav_Menu {

    function display_element( $element, &$children_elements, $max_depth, $depth=0, $args, &$output ) {
        $element->has_children = !empty( $children_elements[$element->ID] );
        $element->classes[] = ( $element->current || $element->current_item_ancestor ) ? 'active' : '';
        $element->classes[] = ( $element->has_children ) ? 'has-dropdown' : '';

        parent::display_element( $element, $children_elements, $max_depth, $depth, $args, $output );
    }

    function start_el( &$output, $object, $depth = 0, $args = array(), $current_object_id = 0 ) {
        $item_html = '';
        parent::start_el( $item_html, $object, $depth, $args ); 

        // $output .= ( $depth == 0 ) ? '<li class="divider"></li>' : '';

        $classes = empty( $object->classes ) ? array() : (array) $object->classes;  

        if( in_array('label', $classes) ) {
            $output .= '<li class="divider"></li>';
            $item_html = preg_replace( '/<a[^>]*>(.*)<\/a>/iU', '<label>$1</label>', $item_html );
        }

    if ( in_array('divider', $classes) ) {
        $item_html = preg_replace( '/<a[^>]*>( .* )<\/a>/iU', '', $item_html );
    }

        $output .= $item_html;
    }

    function start_lvl( &$output, $depth = 0, $args = array() ) {
        $output .= "\n<ul class=\"sub-menu dropdown\">\n";
    }

}

And also don't I have to add it to call it out in my arguments with something like this?

'walker' => new description_walker()

So far everywhere I've tested adding it, has failed.

The fix to have the dropdown work in foundation 5 (WP 4.1) is change in foundation4-topbar.php file, line 2:

from
<nav class="top-bar">
to
<nav class="top-bar" data-topbar>
