            ['label' => 'Войти', 'url' => ['/site/login']]
        ) : (
            '<li>'
            . Html::beginForm(['/site/logout'], 'post')
            . Html::submitButton(
                'Выход (' . Yii::$app->user->identity->username . ')',
                ['class' => 'btn btn-link logout']
            )
            . Html::endForm()
            . '</li>'
        )
    ],
]);
NavBar::end();

There is such a standard code in Yii2, I need to add a dropdown menu to this menu. and move the input button to the right side. I read the documentation and did not understand anything there, because there is nothing like in this example. And I wanted to shift to the right by adding 'class'=>'pull-right' does not work. I've already tried everything, help plz __)))

Answer 1

It’s faster for you to simply insert the layout from Bootstrap and not worry. If you are so tormented with this, then what will happen if you need to somehow make a menu around everything?
There is no difference from using the widget here.

Answer 2

Yii widgets for Bootstrap are a lot of fun. If there are a lot of edits, it's better to immediately demolish and write your own widget or just html. There, a step to the left, a step to the right - execution. They did it for show, only for standard solutions.
Ideally, we make our own (perhaps we inherit from the yuish one), redefine what we need, enjoy life.
