Checkbox group - max options

[Hesesses]

I would like to set max options which can be selected.

For example this would allow to select max 2 options and it would not allow to select 3rd option.

<flux:checkbox.group wire:model="notifications" max="2" label="Notifications">
    <flux:checkbox label="Push notifications" value="push" />
    <flux:checkbox label="Email" value="email" />
    <flux:checkbox label="In-app alerts" value="app" />
    <flux:checkbox label="SMS" value="sms" />
</flux:checkbox.group>
