 Specify a different key for your model.
 For example: you have id, code and parent_code. Your model uses id as key, but the parent-child relation is established between code and parent_code
 
-```PHP
+```php
 ->withKey('code')
 ```
 
 Store fetched models for additional functionality
 
-```PHP
+```php
 ->storeResults()

 Now you can access the results in `disabledOptions` or `hiddenOptions`
 
-```PHP
+```php
 ->disabledOptions(function ($state, SelectTree $component) {
     $results = $component->getResults();
 })
