I ask you how to select multiple day from date-picker. I tried using type:'multi-day'in option property. However, when clicking date-picker, none of date-picker-modal shows in display... And I confirm that when type: 'day' I can use date-picker! Is this Bug?

<template>
    <mdb-container>
        <mdb-row>
            <mdb-col col="2">
                <mdb-date-picker :option="options" />
            </mdb-col>
        </mdb-row>
    </mdb-container>
</template>

<script>
export default {
    data() {
        return {
            options: {
                type: 'multi-day'
            }
        }
    }
}
</script>
