Hoe Widget omzetten naar recursive widgets?

Hallo

heb een widget plugin gemaakt en dat werkt echter deze widget mag je maar 1 keer toekennen. Het zou “recursive widget” moeten zijn maar snap niet hoe ik het aanpas

Dit is mijn code

function knoppenGenerator( ) {
}

// set
function KGCode_widget($args) {
    extract($args);
    $options = get_option('KGCode_widget');

?>
<div class="widget_header_1"><?php echo $options['title_widget'];?>
<div class="widget_header_2"><?php echo $options['text_widget'];?>
<br /><br />
<div class="widget_button">
<div class="widget_button_tekst">

<a class="button_generator_1" style="text-decoration: none;" a href="<?php echo $options['uri'];?>" target="_self">
<?php echo $options['text_knop'];?>
</a>
</div></div>
</div></div>
<?php    

}

// controlls
function KGCode_control() {

    $options = get_option('KGCode_widget');

    if (isset($_POST['KGCodeSubmit'])) {
        $options['title_widget'] = htmlspecialchars($_POST['widgetTitle']);
        $options['text_widget'] = htmlspecialchars($_POST['widgetText']);
        $options['text_knop'] = htmlspecialchars($_POST['widgetknop']);
        $options['uri'] = htmlspecialchars($_POST['widgetUri']);
        update_option('KGCode_widget', $options);
    }
    ?>
    <div class="widget-content">
       <p>
           <label for="widgetTitle" >Title: </label>
           <input type="text" id="widgetTitle" name="widgetTitle" class="QPBG" value="<?php echo $options['title_widget']; ?>" />
       </p>
       <p>
           <label for="widgetText">Omschrijving: </label>
           <input type="text" id="widgetText" name="widgetText" class="QPBG" value="<?php echo $options['text_widget']; ?>" />
       </p>
       <p>
           <label for="widgetknop">Knop text: </label>
           <input type="text" id="widgetknop" name="widgetknop" class="QPBG" value="<?php echo $options['text_knop']; ?>" />
       </p>
       <p>
           <label for="widgetUri">Url: * </label>
           <input type="text" id="widgetUri" name="widgetUri" class="QPBG" value="<?php echo $options['uri']; ?>" />
           <br /><small>* bv /chat</small>
       </p>
       <p>
           <input type="hidden" id="KGCodeSubmit" name="KGCodeSubmit" value="1" />
       </p>
   </div>
   <?php
}

// init
function KGCode_init() {
    wp_register_sidebar_widget('KG_widget', 'Knoppen generator', 'KGCode_widget', null);
    wp_register_widget_control('KG_widget', 'Knoppen generator', 'KGCode_control', null, null);
}

add_action('plugins_loaded', 'KGCode_init');
