Tengo una barra de navegación que funciona, pero cómo obtener una barra de toda la página sobre la barra de navegación (Pagewide div). En la vista móvil, la barra puede desaparecer.

<nav class="navbar fixed-top navbar-expand-lg navbar-dark bg-dark">
            <div>
                Pagewide
            </div>
            <div class="container" style="padding: 0px;">
                <a class="navbar-brand" href="<?php echo $this->url('home'); ?>" target="_self">
                    <img src="<?= $this->basePath('img/logo.png') ?>" style="width: 100%;"/>
                </a>
                <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo02" aria-controls="navbarTogglerDemo02" aria-expanded="false" aria-label="Toggle navigation">
                    <span class="navbar-toggler-icon"></span>
                </button>
                <form class="form-inline my-2 my-lg-0">
                    <input class="form-control form-control-sm mr-sm-2" type="search" placeholder="Search">
                    <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
                </form>
                <div class="collapse navbar-collapse" id="navbarTogglerDemo02">
                    <ul class="navbar-nav ml-auto">
                        <li class="nav-item active">
                            <a class="nav-link" href="<?= $this->basePath('inloggen') ?>">Inloggen<span class="sr-only">(current)</span></a>
                        </li>
                        <li class="nav-item">
                            <a class="nav-link" href="#">Link</a>
                        </li>
                        <li class="nav-item">
                            <a class="nav-link disabled" href="#">Disabled</a>
                        </li>
                    </ul>
                </div>   
            </div>
        </nav>
