Filtering
To enable the filtering functionality, set the filterable property to true.
Basic Configuration
When the filtering functionality is enabled, the DropDownTree component renders a filter input in the drop-down list. On every character input, the DropDownTree triggers a onFilterChange event. The event argument contains the typed string value that you can use to filter the source.
