(Yii2) How to display link with parameters in yii\bootstrap\Nav widget?

Question

Yii

I am using the yii\bootstrap\Nav widget to display the menu.
I'm trying to specify a link to a user profile in one of the Menu Items:

'url' => ['/user/index&id=' . Yii::$app->user->identity->id],

The page is displayed as /index.php?r=user%2Findex%26id%3D and an error pops up during the transition:
Unable to resolve the request: user/index&id=1
If I change href to /index.php?r=user% through Firebug 2Findex&id=1 , then everything works fine.
