The way your function works, your input array needs to be adjusted to this:

 

$data = array('id'=>'nav', 'menu' => array ('menu1' =>'home',
                                         'menu2' =>'create_post',
                                         'menu3' =>'contact',
                                         'menu4' =>'about'),
);
