+## Using types
+
+The [underlying tags package](https://github.com/spatie/laravel-tags) has support for [tag types](https://docs.spatie.be/laravel-tags/v2/advanced-usage/using-types). To make your tags field save tags of a certain type just tack on the name of type when adding the field to your Nova resource.
+
+```php
+// in your Nova resource
+
+public function fields(Request $request)
+{
+    return [
+        // ...
+
+        Tags::make('Tags')->type('my-special-type'),
