How to style Yii2 menu widget?

Question

Yii

Hello! I can’t catch up with how this is done in Yii2, many properties have been removed from Yii1,
how to implement such a menu? :

<ul class="nav navbar-nav width-sto">
                        <li class="active"><a href="/index.html">Главная</a></li>
                        <li class="dropdown">
                            <a class="dropdown-toggle" href="/apple.html">Apple<b class="caret"></b></a>
                            <ul role="menu" class="dropdown-menu">
                                <li><a href="/iphone.html">iPhone</a></li>
                                <li><a href="/ipad.html">iPad</a></li>
                                <li><a href="/macbook-i-imac.html">Macbook и iMac</a></li>
                                <li><a href="/ipod-touch.html">iPod Touch</a></li>
                            </ul>
                        </li>
                        <li class="dropdown">
                            <a class="dropdown-toggle" href="/samsung.html">Samsung<b class="caret"></b></a>
                            <ul role="menu" class="dropdown-menu">
                                <li><a href="/smartphones-samsung.html">Смартфоны</a></li>
                                <li><a href="/tablets-samsung.html">Планшеты</a></li>
                            </ul>
                        </li>
                        <li><a href="/price.html">Прайс-лист</a></li>
                        <li><a href="/contacts.html">Контакты</a></li>
                    </ul>

What can I add here? :

echo \yii\widgets\Menu::widget([
                        'items' => MenuModel::getItemsByMenuId(1),
                        'options'=>[
                            'class' => 'nav navbar-nav width-sto'
                        ],
                        'activateParents'=>true,
                        'activeCssClass'=>'active',
                        
                    ]);
