How to apply a different menu styling to the front page?

Question

I'm trying to figure out how to get a second menustyling on a WordPress site that I use fullpage.js on.

I have a custom walker and the menu works by anchorlinks to slides. I'm trying to figure out how to change the styling on the menu for slides, so the front page has its own.

Site: http://www.svenssonsbild.se/Svenssonsbild2

Loop: 

<?php

if (($locations = get_nav_menu_locations()) && $locations['slides'] ) {

    $menu = wp_get_nav_menu_object( $locations['slides'] );
    $menu_items = wp_get_nav_menu_items($menu->term_id);
    $pageID = array();

    foreach($menu_items as $item) {
        if($item->object == 'page')
        $pageID[] = $item->object_id;

    }
    query_posts( array( 'post_type' => 'page','post__in' => $pageID, 'posts_per_page' =>      
    count($pageID), 'orderby' => 'post__in' ) );

}


while(have_posts() ) : the_post();

?> 


<!--     <div id="<?php echo $post->post_name;?>" class="section"> -->

<div id="pageSlide-<?php echo $post->post_name;?>" class="section" data-anchor="<?php echo $post->post_name;?>">

walker:

<?php 
class description_walker extends Walker_Nav_Menu {

    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;
        $class_names = join(' ', apply_filters('nav_menu_css_class', array_filter($classes), $item));
        $class_names = ' class="'.esc_attr($class_names).'"';
        $output     .= $indent.'<li id="menu-item-'.$item->ID.'"'.$value.$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($item->xfn).'"':'';
        if($item->object == 'page') {
            $varpost = get_post($item->object_id);
            if(is_home()) {
                $attributes .= ' href="#'.$varpost->post_name.'"';
            }
            else {
                $attributes .= ' href="'.home_url().'/#'.$varpost->post_name.'"';
            }
        }
        else 
            $attributes .= !empty($item->url)?' href="'.esc_attr($item->url).'"':'';
        $item_output     = $args->before;
        $item_output    .= '<a'.$attributes.'>';
        $item_output    .= $args->link_before.apply_filters('the_title', $item->title, $item->ID);
        $item_output    .= $args->link_after;
        $item_output    .= '</a>';
        $item_output    .= $args->after;
        $output         .= apply_filters('walker_nav_menu_start_el', $item_output, $item, $depth, $args);
    }
}
?>

Solution

If you just want to apply a different style for the first section (not slide, slides are horizontal) you probably want to do it by using the plugin callbacks such as afterLoad or onLeave.

Something like:

$.fn.fullpage({
    slidesColor: ['red', 'blue'],
    afterLoad: function (anchorLink, index) {
        //if it is not in the 1st section, we apply sectionMenu class
        if (index !=1 ) {
            $('.demo').addClass('sectionMenu');
        }

        //otherwise, we remove it
        else{
            $('.demo').removeClass('sectionMenu');
        }
    }
});

OTHER TIPS

Use the wordpress body class

on the homepage the body tag will have a class of home like so <body class="home">

So on the homepage target the menu like so:

.home .your-menu-selector
