Hi,
i would ask, if there is a bug with clonable group on setting page. Here is sample code:
With this code, on admin site i get only one input (type "text" with id "mb_top_posts") - so not textarea, no checkbox field.
$prefix = 'mb_';
$meta_boxes[] = array(
'id' => 'top_i',
'title' => ' ',
'settings_pages' => 'top-positions',
'tab' => 'position_i',
'fields' => array(
array(
'id' => "{$prefix}top_posts",
'type' => 'group',
'clone' => true,
'fields' => array(
array(
'name' => __('Perex','textdomain'),
'id' => "{$prefix}perex",
'type' => 'textarea'
),
array(
'name' => __('Hide',TEXTDOMAIN),
'id' => "{$prefix}hide",
'type' => 'checkbox'
),
)
)
)
);
(WP 4.7.5, latest metabox plugin and addons)
.
