This sample demonstrates the CheckBox functionalities of the TreeView. Click on any parent node's CheckBox to check/uncheck the node and its child nodes. The parent node's checked state will be determined by its child nodes checked state.
The TreeView component can be rendered with checkbox on the left side of each tree node. This allows the user to check more than one nodes, and this can be enabled by the showCheckBox property.
In this demo, the TreeView is populated with checkbox enabled.
More information about Treeview can be found in this documentation section .
