 * Hi there,
 * I’d be most grateful to anyone that can shed any light on this – I’ve studied
   the documentation and I can’t see why this doesn’t work.
 * I’m trying to create a navigation list which will look something like this:
 *     ```
       <ul>
         <li>
           <ul>
             <li></li>
             <li></li>
             <li></li>
           </ul>
           <ul>
             <li></li>
             <li></li>
             <li></li>
           </ul>
         </li>
         <li>
           <ul>
             <li></li>
             <li></li>
             <li></li>
           </ul>
           <ul>
             <li></li>
             <li></li>
             <li></li>
           </ul>
         </li>
        </ul>
       ```
   
 * It requires 3 loops: a country loop, and then within that a city loop and a town
   loop (to list cities and towns within a country).
 * I’m using the following code:
 *     ```
       <ul>
   
       <?php
       	# GET Countries
       	 $countryArgs = array(
       	   'category_name' => 'country',
       	   'posts_per_page' => -1,
       	   'meta_key' => 'country-menu-order',
       	   'orderby' => 'meta_value_num',
       	   'order' => 'ASC'
       	 );
         	$sidebar_nav_loop = new WP_Query($countryArgs);
   
         	if( $sidebar_nav_loop->have_posts() ):
   
         		while( $sidebar_nav_loop->have_posts() ): $sidebar_nav_loop->the_post();
   
       		?>
   
                    <li class="<?php echo basename(get_permalink()); ?>"> <a href="<?php echo get_permalink(); ?>"> <?php the_title(); ?> </a>
   
       			 <?php
                    # GET RELATED Cities
                    $cityArgs = array(
                                   'post_type' 		=> 'post',
                                   'posts_per_page' 	=> -1,
                                   'meta_key'			=> 'city-group',
                                   'orderby'			=> 'meta_value_num',
                                   'order'			 	=> 'ASC',
                                   'meta_query' 		=> array(
                                       array(
                                           'key' 		=> 'city-country',
                                           'value' 	=> '"' . get_the_ID() . '"',
                                           'compare' 	=> 'LIKE'
                                       )
                                   )
                               );
                   $city_loop = new WP_Query($cityArgs);

       					endwhile;
   
                        echo "</ul>";
   
       			 endif;
       			 wp_reset_postdata();
   
       			?>
   
                   <?php

                   	</li>
        			<?php
       			 endwhile;
   
       			 echo "</ul>";

 * I can get the country and city to work, or the country and town, but I can’t 
   get all three! To the best of my knowledge I’ve followed the documentation and
   reset the queries so they shouldn’t conflict.
 * Many thanks in advance for any help!

 * Just a guess, but I think the wp_reset_postdata() may be the problem.
 * You are using get_the_ID() in your query parameters, but if you reset the postdata,
   it will get the wrong ID. Try not resetting the postdata until after all 3 loops
   have finished.
