    'items' => [
        ['label' => 'Home', 'url' => ['/site/index'], 'options' => ['class' => 'bold']],
        ['label' => 'About', 'url' => ['/site/about']],
        ['label' => 'Contact', 'url' => ['/site/contact']],
    ],
]);

.bold {
    font-weight: bold;
}

echo \yii\widgets\Menu::widget([
    'items' => [
        ['label' => '<strong>Home</strong>', 'url' => ['/site/index']],
        ['label' => '<strong>About</strong>', 'url' => ['/site/about']],
        ['label' => '<strong>Contact</strong>', 'url' => ['/site/contact']],
    ],
    'encodeLabels' => false, // 禁用对标签进行HTML编码
]);

use yii\bootstrap\Nav;

echo Nav::widget([
    'items' => [
        [
            'label' => '<span class="glyphicon glyphicon-home"></span> Home',
            'url' => ['/site/index'],
            'encode' => false, // 禁用对标签进行HTML编码
        ],
        ['label' => 'About', 'url' => ['/site/about']],
        ['label' => 'Contact', 'url' => ['/site/contact']],
    ],
