 Route groups may also be used to handle sub-domain routing. Sub-domains may be assigned route parameters just like route URIs, allowing you to capture a portion of the sub-domain for usage in your route or controller. The sub-domain may be specified using the `domain` key on the group attribute array:

+## Partial groups
+
+Partial router groups has the same benefits as a normal group, but supports parameters and are only rendered when the url is matched.
+
+This can be extremely useful in situations where you only want certain routes added when certain criteria has been met.
+
+**NOTE:** Use partial groups with caution as routes added within are only rendered and available once the url of the partial-group has matched. This can cause `url()` not to find urls for the routes added within.
+
+**Example:**
+
+```php
+SimpleRouter::partialGroup('/admin/{applicationId}', function ($applicationId) {
+
+    // Routes within are rendered when the group matches
+
+    // The url "/admin/{applicationId}" will be prepended to any routes added here.
+
+});
+```

 ## Form Method Spoofing
 
 HTML forms do not support `PUT`, `PATCH` or `DELETE` actions. So, when defining `PUT`, `PATCH` or `DELETE` routes that are called from an HTML form, you will need to add a hidden `_method` field to the form. The value sent with the `_method` field will be used as the HTTP request method:
