/**
 * Represents the Kendo UI for Angular [MultiSelectTree](https://www.telerik.com/kendo-angular-ui/components/dropdowns/multiselecttree) component.
 *
 * The `MultiSelectTree` lets you select multiple items from hierarchical data in a tree structure.
 * It provides built-in filtering, checkboxes, and adaptive rendering for mobile devices.
 *
 * @example
 * ```typescript
 * @Component({
 *   selector: 'my-app',
 *   template: `
 *     <kendo-multiselecttree
 *       [data]="data"
 *       textField="text"
 *       valueField="value"
 *       [(value)]="selectedValues">
 *     </kendo-multiselecttree>
 *   `
 * })
 * export class AppComponent {
 *   public data = [
 *     { text: 'Root', value: 1, items: [
 *       { text: 'Child 1', value: 2 },
 *       { text: 'Child 2', value: 3 }
 *     ]}
 *   ];
 *   public selectedValues = [2, 3];
 * }
 * ```
 * @remarks
 * Supported children components are: {@link CustomMessagesComponent}.
