Yii Why doesn't this construction work?

Question

Yii

Why doesn't the menu template change, it says in the docs that it can be changed, but nothing happens...
Here is the code,

echo Menu::widget([            
               'items' => [
                   ['label' => 'Главная', 'url' => ['site/index']],
                   ['label' => 'Все посты', 'url' => ['site/buy']]
               ],
                'labelTemplate' => '{label}',
                 'submenuTemplate' => '<div class="main_menu">{items}</div>'
            ]);

Good morning.
It is also in the documentation linkTemplateand can be further configured in items
ps. These are just guesses what exactly you need. Describe in detail, with an example of the html you want to get.
