How to display subcategories in wordpress menu

Hello I have a script that displays all categories in wordpress menu but I want to add subcategories to this menu too. How I can check if categories have subcategories then display them in submenu of category.

$items .= '<ul class="sub-menu">';  
$categories = get_categories();  
foreach ($categories as $category) {
    $option = '<li><a href="'.get_category_link( $category->term_id ).'">';
    $option .= $category->cat_name;
    $option .= '</a></li>';         
    $items .= $option;
}    
$items .= '</ul></li>';

get_categories() only fetches categories and subcategories those are assigned to any post(s) unless you pass array("hide_empty"=>0) as parameter to fetch inactive categories/subcategories too

try below

$items .= '<ul class="sub-menu">';  
$categories = get_categories(array("hide_empty"=>0,'parent'=> '0'));  
foreach ($categories as $category) {
    $childrens = get_categories(array('child_of'=>$category->term_id,"hide_empty"=>0));
    $subitems ='';
    if(count($childrens)>0){
        $subitems .= '<ul class="sub-menu">';  
        foreach($childrens as $children){
            $opt = '<li><a href="'.get_category_link($children->term_id ).'">';
            $opt .= $children->cat_name;
            $opt .= '</a></li>';         
            $subitems .= $opt;  
        }
        $subitems.= '</ul></li>';
    }
    $option = '<li><a href="'.get_category_link( $category->term_id ).'">';
    $option .= $category->cat_name;
    $option .= '</a>'.$subitems.'</li>';         
    $items .= $option;
}    
$items .= '</ul></li>';

I know its a dirty way. Don't use "hide_empty"=>0 unless you really need it
