# TreeList Aggregates

The `TreeList` component allows you to display aggregated data. In order to render aggregated data, it should be calculated and added to the TreeList [`dataItems`](https://www.telerik.com/kendo-vue-ui-develop/components/treelist/api/treelistprops#dataitems) value.

## Getting Started
