ButtonToolbar Combines sets of button groups into button toolbars for more complex components.

Use utility classes as needed to space out groups, buttons, and more.

For example,

// a button toolbar with items configuration
echo ButtonToolbar::widget([
    'buttonGroups' => [
        [
            'buttons' => [
                ['label' => '1', 'options' => ['class' => ['btn-secondary']]],
                ['label' => '2', 'options' => ['class' => ['btn-secondary']]],
                ['label' => '3', 'options' => ['class' => ['btn-secondary']]],
                ['label' => '4', 'options' => ['class' => ['btn-secondary']]]
            ],
             'class' => ['mr-2']
        ],
        [
            'buttons' => [
                ['label' => '5', 'options' => ['class' => ['btn-secondary']]],
                ['label' => '6', 'options' => ['class' => ['btn-secondary']]],
                ['label' => '7', 'options' => ['class' => ['btn-secondary']]]
            ],
            'class' => ['mr-2']
        ],
        [
            'buttons' => [
                ['label' => '8', 'options' => ['class' => ['btn-secondary']]]
            ]
        ]
    ]
]);

Pressing on the button should be handled via JavaScript. See the following for details:
