stamen maps is based on openstreetmap and
Basic Google Maps Placemarks is based on Google Maps. So it won’t work! ??

You are my hero. Thanks for the help, it works!
I have changed the code on line 14 from AND tt.term_id = ‘%d’ to AND tt.term_id IN($catid) because with the other one I can only get one $catid now I can put in more more.

function get_meta_values( $key = '', $catid = '' , $type = 'post', $status = 'publish', $tax = 'category') {
    global $wpdb;
if( empty( $catid ) ) $catid = '1';
    if( empty( $key ) )
        return;
    $r = $wpdb->get_results( $wpdb->prepare( "
        SELECT p.ID, pm.meta_value FROM {$wpdb->postmeta} pm
        LEFT JOIN {$wpdb->posts} p ON p.ID = pm.post_id
        LEFT JOIN {$wpdb->term_relationships} tr ON p.ID = tr.object_id
        LEFT JOIN {$wpdb->term_taxonomy} tt ON tr.term_taxonomy_id = tt.term_taxonomy_id
        WHERE pm.meta_key = '%s'
        AND p.post_status = '%s'
        AND p.post_type = '%s'
        AND tt.taxonomy = '%s'
        AND tt.term_id IN($catid)
    ", $key, $status, $type, $tax, $catid ));

    foreach ( $r as $my_r )
        $metas[$my_r->ID] = $my_r->meta_value;

    return $metas;
}

Get Values:
$myarray = get_meta_values( 'my_meta_key', '1,2' );

You can use :before

<style type="text/css">
.addFav:before {background:url(https://lorempixel.com/400/200/sports) no-repeat; height:200px; width:400px; position:absolute; content:""; opacity:1;}
.addFav:hover:before { opacity:0.2; }
.addFav { height:200px; width:400px;}
?</style>

<div class=”addFav”>Your Text</div>

Hi,
I hope I understood what you meant.

The category “Recipe” must be the parent category of “Baking” and “Baking” must be the parent category of “Bread”.

You can adjust it under Posts/categories: Edit category.

PS. Sorry for the bad english too! ??

This will work:

<?php
$childcategories = get_categories('child_of=' . $cat . '&hide_empty=1');
foreach ($childcategories as $childcategory) {
if (in_category($childcategory)) {
$childs  = array($childcategory->cat_ID);
foreach($childs as $idofchild){$string .= $idofchild.',';} } }
$args = array( 'taxonomy' => 'category','include' => $string);
wp_tag_cloud( $args);
 ?>

And here a Version for all descendant categories:

<?php
$childcategories = get_categories('child_of=' . $cat . '&hide_empty=1');
foreach ($childcategories as $childcategory) {
$childs  = array($childcategory->cat_ID);
foreach($childs as $idofchild){$string .= $idofchild.',';} }
$args = array( 'taxonomy' => 'category','include' => $string);
wp_tag_cloud( $args);
 ?>
