Yii2 remove action index

I would like to have urls like this for my project:

domain/ (site/index)

domain/contact.html (site/contact)

domain/about.html (site/about)

domain/some-stuff.html (site/some-stuff)

The only problem i have is the index action from the siteController. I want it to point to dommain/ but when i hide the controller via urlManager and turn on suffix the navWidget generates ‘/.html’ for the first item.


'items' => [

            ['label' => 'Home', 'url' => ['/']],

            ['label' => 'About', 'url' => ['/site/about']],

            ['label' => 'Contact', 'url' => ['/site/contact']],




'urlManager' => [

	'class' => 'yii\web\UrlManager',

        'enablePrettyUrl' => true,

        'showScriptName' => false,

	'suffix' => '.html',

	'rules' => [

		'<alias:index|contact|about>' => 'site/<alias>', 			  



Do i need to use the .htaccess for this?
