    ]) ?>
</div>

Best practices

You can unify building of site breadcrumbs navigation by extending yii\base\Module. It will guarantee what all modules in requested route gets their place in breadcrumbs widget. Example:

use yii\base\Module as BaseModule;
use itnelo\filters\BreadcrumbsFilter;

class Module extends BaseModule
{
    /**
     * Module name
     * @var string
     */
    public $name = 'My Module';

    /**
     * Enable/Disable breadcrumbs natigation via app\components\filters\BreadcrumbsFilter
     * For module and submodules, without affects on parent module
     * @var bool
     */
    public $breadcrumbs = true;

    /**
     * Array of [routes|controllers|actions] names which shouldn't have breadcrumbs
     * ['*'] means what breadcrumbs navigation disabled for all controllers and actions (direct childs)
     * For module and submodules, without affects on parent module
     * @var bool
     */
    public $breadcrumbsExceptRoutes = [];

    /**
     * @inheritdoc
     */
    public function behaviors()
    {
        $behaviors = [];

        if ($this->breadcrumbs) {
            $behaviors['breadcrumbs'] = [
                'class' => BreadcrumbsFilter::className(),
                'label' => $this->name,
                'defaultRoute' => $this->defaultRoute,
                'exceptRoutes' => $this->breadcrumbsExceptRoutes,
            ];
        }

        return array_merge(parent::behaviors(), $behaviors);
    }
}
