+Sometimes you may need a method to be chained on a field based on another condition. Backpack takes advantage of <a href="https://laravel.com/docs/10.x/queries#conditional-clauses" target="_blank">Laravel Conditionable</a> to easily let you accomplish that. You can either use ```->when()``` or ```unless()```:

+    ->when($condition, function ($field) {
+        $field->hint('My hint');
