CascadeOnCustomValue

configuration

Applicable to a parent MultiColumnComboBox in a cascading scenario. If set to true cascading will be triggered upon custom input in the parent widget. When set to false (default) the child will not cascade and it will be disabled upon setting custom input in the parent MultiColumnComboBox. Cascade on custom values works only when cascadeFromParentField is not set for the child combo, or it points to the dataValueField of the parent.

cascadeOnCustomValue

Boolean

Default: false
