How to disable navbar-toggle?

Question

Yii

Good afternoon. I would like to disable the button that the standard Navbar widget generates. Found that there is a method renderToggleButton(). But how to use it?

<?php
                NavBar::begin([
                    'brandLabel' => FALSE,
                    'brandUrl' => Yii::$app->homeUrl,
                    'options' => [
                        'class' => 'navbar navbar-default navbar-fixed-top',
                        'id' => 'mainNav',
                        'renderToggleButton' => 'false'
                    ],
                ]);
                ?>

Where to stick it?

Answer 1

If we are talking about standard yii2-app-basic or advanced, then you can find it in app/frontend/views/layouts/main.php folder for advanced or app/views/layouts/main.php for basic. NavBar is initialized there, and changes should be made there.
upd:
To make changes to the widget itself, you can add the CustomNavBar extends yii\bootstrap\NavBar class to the widgets folder, and... the simplest solution is to override the renderToggleButton function;
renderToggleButton() {return ''}
and in layouts/main.php instead of use yii\bootstrap\NavBar; write use app\widgets\CustomNavBar;
Because in the standard NavBar bootstrap, the renderToggleButton() function is executed regardless of options and cannot be disabled by the settings array.
