# TreeList Virtual Scrolling

The Kendo UI for Vue `TreeList` provides Virtual scrolling as an alternative to the [data paging](https://www.telerik.com/kendo-vue-ui-develop/components/treelist/paging).

The Virtualization functionality is suitable for scenarios with a big number of data items. When working in a Virtualization mode, the TreeList renders only part the component's data, based on the scroller position.

## Getting Started

To use the TreeList with virtual scrolling you need to set the following configurations:

* Set the [`scrollable`](https://www.telerik.com/kendo-vue-ui-develop/components/treelist/api/treelistprops#scrollable) prop to `virtual`.
* Set the TreeList height in pixels through its [`style`](https://www.telerik.com/kendo-vue-ui-develop/components/treelist/api/treelistprops#wrapperstyle) prop.
* Set the [`rowHeight`](https://www.telerik.com/kendo-vue-ui-develop/components/treelist/api/treelistprops#rowheight) prop.
