+- **Data Binding**    
+TreeList can load and update data from different [data source](/Documentation/ApiReference/UI_Components/dxTreeList/Configuration/#dataSource) types. You can define data as [plain or hierarchical](/Documentation/ApiReference/UI_Components/dxTreeList/Configuration/#dataStructure). If you choose plain data, you can load it [on demand](/Documentation/ApiReference/UI_Components/dxTreeList/Configuration/#hasItemsExpr).
+
+- **Various Edit Modes**    
+[Edit](/concepts/05%20UI%20Components/TreeList/20%20Editing '/Documentation/Guide/UI_Components/TreeList/Editing/') TreeList data in multiple modes, including [form](/concepts/05%20UI%20Components/TreeList/20%20Editing/10%20User%20Interaction/40%20Form%20Mode.md '/Documentation/Guide/UI_Components/TreeList/Editing/#User_Interaction/Form_Mode') and [popup](/concepts/05%20UI%20Components/TreeList/20%20Editing/10%20User%20Interaction/50%20Popup%20Mode.md '/Documentation/Guide/UI_Components/TreeList/Editing/#User_Interaction/Popup_Mode') modes.
+
+- **Filtering and Sorting**    
+Set up a [filter row](/concepts/05%20UI%20Components/TreeList/30%20Filtering%20and%20Searching/1%20Filter%20Row.md '/Documentation/Guide/UI_Components/TreeList/Filtering_and_Searching/#Filter_Row') and a [header filter](/concepts/05%20UI%20Components/TreeList/30%20Filtering%20and%20Searching/2%20Header%20Filter.md '/Documentation/Guide/UI_Components/TreeList/Filtering_and_Searching/#Header_Filter') to filter data by column values, or use other [ways to filter](/concepts/05%20UI%20Components/TreeList/30%20Filtering%20and%20Searching '/Documentation/Guide/UI_Components/TreeList/Filtering_and_Searching/'). You can [sort](/concepts/05%20UI%20Components/TreeList/25%20Sorting/10%20User%20Interaction.md '/Documentation/Guide/UI_Components/TreeList/Sorting/#User_Interaction') TreeList by single or multiple columns initially or at runtime.
+
+- **Rich Customization**    
+TreeList offers extensive appearance and behavior customization.
+
+- **Nodes Drag and Drop**    
+You can [drag and drop](/Documentation/Guide/UI_Components/TreeList/Getting_Started_with_TreeList/#Enable_Row_Drag_&_Drop) nodes to reorder them or change their hierarchy.
