Can't redirect from subdomain to main domain

Question

I have 2 projects. First project is in the main domain and the second project is in a subdomain. When I click on a menu item to redirect from subdomain to main domain, it redirects me to: https://subdomain.maindomain.com/https://maindomain.com/

Code:

echo Nav::widget([
    'options' => ['class' => 'navbar-nav navbar-right'],
    'items' => [
        ['label' => 'Menu 1', 'url' => ['https://maindomain.com/']],
        ['label' => 'Menu 2', 'url' => ['https://maindomain.com/1']],
    ],
]);

So I need just redirect to https://maindomain.com/ when click to menu in subdomain project.

Answer 1

Try putting URL outside of brackets. e.g.:

['label' => 'Menu 1', 'url' => 'https://maindomain.com/'],
