* ```php
* // Example 1
* [
* 'class' => 'kartik\grid\EnumColumn',
* 'attribute' => 'role',
* 'enum' => User::getRoles(),
* 'loadEnumAsFilter' => true, // optional - defaults to `true`
* ],
* // Example 2
* [
* 'class' => 'kartik\grid\EnumColumn',
* 'attribute' => 'gender',
* 'enum' => [
* '0' => '<span class="text-muted">Unknown</span>',
* 'F' => '<span class="text-success">Female</span>',
* 'M' => '<span class="text-danger">Male</span>',
* ],
* 'filter' => [ // will override the grid column filter
* '0' => 'Unknown',
* 'F' => 'Female',
* 'M' => 'Male',
* ],
