Answer 1

您正在寻找这样的事情吗？

为sideName示例提供一个简单的

 $menuGiiItems[] = ['label' => Yii::t('app','Gii Generators'),  'icon' => 'th-list', 'url'=>Url::to(['/gii'])],

                ['label' => Yii::t('app','Generator 2'),  'url'=>Url::to(['/auth/item'])],
                ['label' => Yii::t('app','Generator 3'),  'url'=>Url::to(['auth/item-child'])],
                ['label' => Yii::t('app','Generator 4'), 'url'=>Url::to(['/auth/rule'])];
                $type = SideNav::TYPE_PRIMARY;
                $heading = '<i class="glyphicon glyphicon-education"></i> ' . Yii::t('app',' Gii - Development Automation ');
                echo SideNav::widget([
                    'type' => $type,
                    'encodeLabels' => false,
                    'heading' => $heading,
                    'items' =>$menuGiiItems,
                ]);

或更复杂的嵌套项目

        $menuItems[] = ['label' => 'DFenX - Yii2 User - '. Yii::t('app','Authentication manager'),  'icon' => 'user', 'items' => [
            ['label' => '/user/admin/index',       'icon' => 'list', 'url'=>Url::to(['/user/admin/index'])],
            ['label' => '/user/1 (view)', 'icon' =>'eye-open', 'url'=>Url::to(['/user/1'])],
            ['label' => 'Settings', 'icon' => 'cog', 'items' => [
                ['label' => '/user/settings', 'icon' => 'cog', 'url'=>Url::to(['/user/settings'])],
                ['label' => '/user/settings/profile',  'url'=>Url::to(['/user/settings/profile'])],
                ['label' => '/user/settings/account',  'url'=>Url::to(['user/settings/account'])],
                ['label' => '/user/settings/networks', 'url'=>Url::to(['/user/settings/networks'])],
            ]],
            ['label' => 'Registration', 'icon' => 'user', 'items' => [                                
                ['label' => '/user/registration/register', 'icon' => 'user', 'url'=>Url::to(['/user/registration/register'])],
                ['label' => '/user/registration/resend', 'icon' => 'user', 'url'=>Url::to(['/user/registration/resend'])],
            ]],
            ['label' => 'Security', 'icon' => 'user', 'items' => [                                
                ['label' => '/user/security/login', 'icon' => 'user', 'url'=>Url::to(['/user/security/login'])],
                ['label' => '/user/security/logout', 'icon' => 'user', 'url'=>Url::to(['/user/security/logout'])],
            ]],
            ['label' => 'Recovery', 'icon' => 'user', 'items'  => [                               
                ['label' => '/user/recovery/request', 'icon' => 'user', 'url'=>Url::to(['/user/recovery/request'])],
                ['label' => '/user/recovery/reset', 'icon' => 'user', 'url'=>Url::to(['/user/recovery/reset'])],
            ]],
        ]];

        $type = SideNav::TYPE_PRIMARY;
        $heading = '<i class="glyphicon glyphicon-tasks"></i> ' . Yii::t('app','AUTHENTICATION');
        //$heading = ['label' => 'Books', 'icon' => 'book'] ;                
        echo SideNav::widget([
            'type' => $type,
            'encodeLabels' => false,
            'heading' => $heading,
            'items' =>$menuItems,
        ]);

好吧，最后我决定使用扩展程序“yii2-menu”。并满足了我的需要。 感谢

Answer 3

$item = [];
    $Category = Category::find()->all();
    $count=0;
    foreach($Category as $model) {
        $item[] = ['label' => $model->description, 'url' => '#'];
        $Subcat = Subcat::find()->where("category_id=$model->id")->all();
        $cnt=0;
        foreach($Subcat as $model2) {
            $item[$count]['items'][$cnt] = ['label' => $model2->description, 'url' => '#'];
            $cnt++;
        }
        $count++;
    }

    echo SideNav::widget([
    'items' => $item,
    )];
