Hi James,
I have a flexible content field called “menu” (it’s a Restaurant menu), which has a repeater field, where each repeater field has a title. I want each title of this section as a dropdown menu for the corresponding page in the menu.
See below my export of the particular field:

)I’d want the “Categorie” sub_field in my menu. I’m using a custom walker, the entire code can be seen below. It works, as long as the repeater field is the 2nd field in my flexible content.
class Cusom_Menu extends Walker_Nav_Menu {
static $count=0;
function start_el(&$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="page-item-'. $item->object_id .' ' . esc_attr( $class_names ) . '"';
if ($depth==0) self::$count=0; // reset var when we are in first level
if ($depth==1 && self::$count==1) { // if we are in submenu and items count is 1...
$output .= '<li class="terug mobile-only"><a href="#"><i class="fa fa-lg fa-chevron-left" aria-hidden="true"></i> Terug</a></li>';
$parent = $item->menu_item_parent;
$output .= '<li class="mobile-only"><a class="hoofd-item" href="#">hoi' . $parent->ID .'</a></li></a></li>';
}
$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 ) .'"' : '';
$attributes .= ! empty( $item->url ) ? ' href="' . esc_attr( $item->url ) .'"' : '';
$parent = wp_get_post_parent_id($item->object_id);
$thumbnail = '';
if ( has_post_thumbnail( $item->object_id ) and 1 == $depth ) {
$thumbnail = get_the_post_thumbnail( $item->object_id );
}
$item_output = $args->before;
if (1 == $depth and $thumbnail and $parent == 43){
$item_output .= '<a'. $attributes .' class="hoofdlink">';
$item_output .= '<div class="afbeelding">' . $thumbnail . '</div><span>';
} else {
$item_output .= '<a'. $attributes .' class="link-'. $depth .'">';
}
$item_output .= $args->link_before . apply_filters( 'the_title', $item->title, $item->ID ) . $args->link_after;
if (1 == $depth and $thumbnail and $parent == 43){
$item_output .= '</span>';
}
$item_output .= '</a>';
$repeater_value = get_post_meta($item->object_id, 'flexibele_content_1_menukaart-repeater', true);
if (1 == $depth and $repeater_value and $parent == 43){
for ($i=0; $i<$repeater_value; $i++) {
$meta_key = 'flexibele_content_1_menukaart-repeater_'.$i.'_categorie';
$meta_key = 'flexibele_content_1_menukaart-repeater_'.$i.'_categorie';
$sub_field_value = get_post_meta($item->object_id, $meta_key, true);
$sub_field_link = (str_replace(' ', '-', strtolower($sub_field_value)));
$item_output .= '<div><a class="sublink" href="' . esc_attr( $item->url ) .'#'. $sub_field_link .'">';
$item_output .= $sub_field_value;
$item_output .= '</a></div>';
}
}
$item_output .= $args->after;
$output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );
self::$count++;
}
function start_lvl( &$output, $depth = 0, $args = array() ) {
$indent = str_repeat("\t", $depth);
$output .= "\n$indent<ul class='sub-menu'><div class='wrapper clearfix'>\n";
}
function end_lvl( &$output, $depth = 0, $args = array() ) {
$indent = str_repeat("\t", $depth);
$output .= "$indent</div></ul>\n";
}
