Yii2. How to remove classes generated by Yii in widgets?

Question

css

I am using the NavBar widget. Code like this:

<?php NavBar::begin([
             'renderInnerContainer' => false,
             'options' => [
                      'renderInnerContainer' => false,
                      'tag' => 'div',
                      'class' => 'row',
             ],
 ]); ?>
...
<?php NavBar::end(); ?>

As a result, I get this HTML:

<div id="w0" class="row navbar" role="navigation">
...
</div>

In the widget settings I registered the class "row", and at the output I get "row navbar". How can I get rid of the "navbar" class?

Answer 1

Redefine the class with your own and business.

class NavBar extends \yii\bootstrap\NavBar
{
    public function init()
    {
        parent::init();
        Html::removeCssClass($this->options, 'navbar');
    }
}

Answer 2

I really don't recommend doing that. Six months later, you will forget that something has changed there, and when you update the widget, everything will be overwritten, if you really want to delete the class, do it through jQuery.
$('#w0').removeClass('navbar');

Answer 3

Or maybe just use yii\widgets\Menu instead of yii\bootstrap\NavBar?

Answer 4

In general, I didn’t come up with anything better than getting into the source code of the widget and commenting out the line adding this class there.
The question is valid. I would like a more elegant solution.
// Update
It's better not to comment the line, but rewrite it like this:

if (!isset($this->options['class'])){
            Html::addCssClass($this->options, 'navbar');
}

If you just comment out the line, then in the case when the class is not explicitly set, an exception will be thrown.
