Enforcing the Validity State

The DropDownTree enables you to set its validity state by utilizing its exposed props. Setting the validity state allows for the implementation of complex validation scenarios. To override the current validity state and apply the corresponding styles, use the valid prop.

Disabling the Validation Styling

By default, to achieve a visual representation of its invalid state, the DropDownTree applies the k-state-invalid class name to the wrapping component. To disable the utilization of k-state-invalid, set the validityStyles property to false.
