/**
* Represents a directive that handles flat data binding and provides built-in filtering functionality for the TreeView.
*
* Use this directive to bind flat data where parent-child relationships are defined by ID fields.
* The directive also enables the built-in filter input and automatic filter handling when used with the `filterable` property.
*
* @example
* ```html
* <kendo-treeview
* kendoTreeViewFlatDataBinding
* idField="id"
* parentIdField="parentId"
* textField="text"
* [nodes]="data"
* [filterable]="true">
* </kendo-treeview>
* ```
*
* @remarks
* Applied to: {@link TreeViewComponent}
