This component is an extension of the Single Selection Widget node. It allows the definition of an invalid default value as the first of all possible choices that are provided via the input table. An invalid default value could be something such as "Please select...". This enables workflow developers to build workflow logic based on whether a user has already made a selection or not which can be helpful to stop the workflow from executing compute-intensive parts during the launch of a Data App because valid default values are set. Additionally, this component can be easily chained for use cases where the values of the second selection widget are dependend on the values of the first selection widget. An example is available on the KNIME Hub.
