Class kartik\bs5dropdown\ButtonDropdown
ButtonDropdown renders a bootstrap 5.x button dropdown component. It extends the yii\bootstrap5\ButtonDropdown to render a button dropdown component individually, or with a button group, or split button dropdown. The Krajee enhancement adds multi level submenu dropdown capability to the bootstrap default component.
For example,
echo ButtonDropdown::widget([
'label' => 'Action',
'dropdown' => [
'items' => [
['label' => 'DropdownA', 'url' => '/'],
['label' => 'DropdownB', 'url' => '#'],
],
],
]);
