Hi moehrenstein,

I have just updated existing plugin code with following code:

paste this code on page where you want to use. I have done it for product category, You can change code as per your requirements.

function aCatSelect($post, $catSlug){

global $post;
$arr = array(‘slug’=>’product_cat’,
‘replace’=>0,
‘none’=>1,
‘orderby’=>’name’,
‘order’=>’ASC’,
‘multi’=>1);

$obj = new stdClass();
foreach ($arr as $key => $value){
$obj->$key = $value;
}

$options = $obj;
$catSlug = ‘product_cat’;

//$thisPostType = $post->post_type;
if(is_admin()){
$argName = ($options->slug == “category”) ? ‘post_category[]’ : ‘tax_input[‘.$catSlug.’][]’;
}else{
$argName = ($options->slug == “category”) ? ‘post_category[]’ : ‘product_cat[]’;
}
$orderby = $options->orderby;
$order = $options->order;

$depth = ($options->multi) ? 1 : 1; //$options->depth; // 0 – show all levels

$none = ($options->none == 1 && $options->slug != “category”) ? __(‘None’) : 0;

$default_category = get_option(‘default_category’);

$post_categories = wp_get_post_terms( $post->ID, $catSlug );
if (!$post_categories) $post_categories = array(0);

echo ‘<div>’;

$i = 0;
$child_of = 0;
$selected = null;
while( $post_categories[0] && $i < count($post_categories) ){
$c = $post_categories[$i];
if($c->parent == $child_of){
$selected = ($c->term_id) ? $c->term_id : $default_category;

if($child_of > 0) $none = __(‘None’);

$args = array(
‘orderby’ => $orderby,
‘order’ => $order,
‘show_option_none’ => $none,

‘hide_if_empty’ => false );
wp_dropdown_categories( $args );

$child_of = $selected;
$i=0;
}
else $i++;
}

$lastcatargs = array(
