CascadeSelect is used as a controlled component with <i>v-model</i> property along with an <i>options</i> collection. To define the label of a group <i>optionGroupLabel</i> property is needed and also <i>optionGroupChildren</i> is
|
||
|
|
required to define the property that refers to the children of a group. Note that order of the <i>optionGroupChildren</i> matters as it should correspond to the data hierarchy.
