yii2 Collapse折叠组件的应用 [ 2.0 版本 ]

比如yii2权威指南的左侧菜单就是通过Collapse组件实现的，不信可以去看看...那么言归正传，Collapse的实例演示如下

实例

<?php
use yii\bootstrap\Collapse;

echo Collapse::widget([
    'items' => [
        // equivalent to the above
        [
            'label' => '折叠1',
            'content' => '<a href="aaa">--内容1</a>',
            // open its content by default
            'contentOptions' => ['class' => 'in']
        ],
        // another group item
        [
            'label' => '折叠2',
            'content' => '<a href="aaa">--内容2</a>',
        ],
        // if you want to swap out .panel-body with .list-group, you may use the following
        [
            'label' => '折叠3',
            'content' => [
                '<a href="aaa">--内容3-1</a>',
                '<a href="aaa">--内容3-2</a>'
            ],
            'footer' => 'Footer' // the footer label in list-group
        ],
    ]
]);
?>
