            MultiSelect is used as a controlled component with <i>v-model</i> property along with an <i>options</i> collection. Label and value of an option are defined with the <i>optionLabel</i> and <i>optionValue</i> properties respectively.
            Default property name for the <i>optionLabel</i> is <i>label</i> and <i>value</i> for the <i>optionValue</i>. If <i>optionValue</i> is omitted and the object has no <i>value</i> property, the object itself becomes the value of an option.
            Note that, when options are simple primitive values such as a string array, no <i>optionLabel</i> and <i>optionValue</i> would be necessary.
