Using CMB2 Plugin to create text_date metabox (datepicker) How do I save multiple dates? [closed]

In CMB2 you can use the group type to create a repeating fields, then inside the group, you declare the text_date type.

Let’s say you have an Events where you set multiple dates.

$events = new_cmb2_box([
    'id' => 'events_metabox',
    'title' => __('Events', 'text_domain'),
    'object_types' => ...,
    'show_on' => ...,
    ...
]);

$events_group_id = $events->add_field([
    'id' => 'events',
    'type' => 'group',
    'desc' => ...,
    'options' => [
        'group_title' => __('Event Date {#}', 'text_domain'),
        'add_button' => __('New Event Date', 'text_domain'),
        'remove_button' => __('Remove Event Date', 'text_domain')
    ]
]);

$events->add_group_field($events_group_id, [
    'id' => 'event_text_date',
    'name' => __('Event Date', 'text_domain'),
    'desc' => ...,
    'type' => 'text_date'
]);
