Yii2 Kartik SideNav 如何设置'active'选项

Question

我有kartik的sidenav（http://demos.krajee.com/sidenav-demo/profile/default）通过将URL设置为控制器/动作，但不理解如何设置主动选项，以使菜单保持打开状态并选择了正确的菜单项。

我尝试设置'Active'=>'控制器/操作'（见下文）以及'Active'=>'控制器/操作/默认＃演示'，但无济于事。当我确实将其设置为"员工/员工 - 仪表板/默认＃演示"时，它确实会突出显示一个选项卡，但在我在这些选项卡上以相同的方式进行操作时不会更改其他选项卡。原件设置为" active" =>'home'，我认为这只是动作，但对我不起作用。

            $type = SideNav::TYPE_DEFAULT;
            $heading = '<i class="glyphicon glyphicon-cog"></i> Employee Menu';
            $item = '/employee/employee-dashboard/default#demo';
echo SideNav::widget([
                'type' => $type,
                'encodeLabels' => false,
                'heading' => $heading,
                'items' => [
                    // Important: you need to specify url as 'controller/action',
                    // not just as 'controller' even if default action is used.
                    //
                    // NOTE: The variable `$item` is specific to this demo page that determines
                    // which menu item will be activated. You need to accordingly define and pass
                    // such variables to your view object to handle such logic in your application
                    // (to determine the active status).
                    //
                    ['label' => 'Dashboard', 'icon' => 'home', 'url' => Url::to(['/employee/employee-dashboard', 'type'=>$type]), 'active' => ($item == '/employee/employee-dashboard/default#demo')]
                    ['label' => 'Paycheck Info', 'icon' => 'book', 'items' => [
                        ['label' => '<span class="pull-right badge">10</span> W2 Forms', 'url' => Url::to(['/employee/w2-form', 'type'=>$type]), 'active' => ($item == 'w2-form')],

'active'=>($item == 'about')
where
    $item = Yii::$app->controller->action->id;

This is how i used
<?php
    $item = Yii::$app->controller->action->id;
    echo SideNav::widget([
        'type' => SideNav::TYPE_DEFAULT,
        'heading' => 'Options',
        'items' => [
            [
                'url' => Yii::$app->homeUrl,
                'label' => 'Home',
                'icon' => 'home',
                'active'=>($item == 'index')
            ],
            [
                'label' => 'Help',
                'icon' => 'question-sign',
                'items' => [
                    ['label' => 'About', 'icon'=>'info-sign', 'url'=>Yii::$app->homeUrl.'site/about', 'active'=>($item == 'about')],
                    ['label' => 'Contact', 'icon'=>'phone', 'url'=>Yii::$app->homeUrl.'site/contact', 'active'=>($item == 'contact')],
                ],
            ],
        ],
    ]);
?>

如果您想在每个页面上设置活动菜单项，则发现一个解决方案是：

仅使用Sidenav小部件创建一个单独的视图文件（例如Sidemenu.php），该文件接受一个称为" CurrentPage"的参数。

echo SideNav::widget([
    'type' => SideNav::TYPE_DEFAULT,
    'heading' => 'Options',
    'items' => [
       [
          'url' => Url::toRoute('/site/index'),
          'label' => 'Home',
          'icon' => 'file',
          'active'=>($currentPage == 'home'),
       ],
       [
          'url' => Url::toRoute('/site/about'),
          'label' => 'About',
          'icon' => 'file',
          'active'=>($currentPage == 'about'),
       ],

然后在渲染菜单的视图页面中，设置currentPage属性 - 例如：

echo $this->render('sidemenu', ['currentPage'=>'home']);

或 echo $ this->渲染（'sidemenu'，['currentpage'=>'oi']）;
