+If you want to add an wizard icon to the radius field as well, a wizard is shipped with. You only have to add the 
+callback and define the coordinates field relation. 
+
+```php
+$GLOBALS['TL_DCA']['tl_page']['fields']['radius'] = [
+    'label'     => ['Radius', 'Angabe des Radius in Metern'],
+    'inputType' => 'text',
+    'eval'      => [

+        'default'     => 500,
+        'minval'      => 100,
