Hi Kevin,

Having both filtering and drag&drop options by using the built-in directives is possible with flat data. Please see the example below:

On the other hand, if passing hierarchical data to the TreeView component, the developer can implement manual filtering logic by binding to the filterChange event and still use the directives responsible for the drag&drop. Please see our manual filtering example for further reference and the below code example demonstrating a possible implementation of this approach as a workaround until this issue is being resolved:
