Source Keep multiple collapse open (with button to toggle) – Bootstrap 3.

L’astuce consiste à :

Englober l’ensemble des éléments collapse dans une <div> avec un id="accordion".
Rajouter sur les liens, qui au clic ouvrent les parties cachées, des attributs data-parent="#accordion" (dont la valeur fera référence à celle de l’id de la div englobante) et href="#collapseOne" (dont la valeur sera unique pour chaque lien).
Rajouter un attribut id="collapseOne" unique (dont la valeur fera référence à la valeur de l’attribut href placé sur le lien juste au-dessus).

…et à ajouter un bout de code javaScript supplémentaire (voir plus bas).

Code pour un comportement standard

Code standard de Bootstrap, comme vu dans la doc officielle. Le sous menu s’ouvre par-dessus le contenu. La partie .navbar-header et la partie .collapse sont solidaires (imbriquées dans la même <nav class="navbar" />).

<nav class="navbar">
    <div class="navbar-header">
    <button class="navbar-toggle" type="button" data-toggle="collapse" data-target=".js-navbar-collapse">
      <span class="sr-only">Toggle navigation</span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </button>
    <a class="navbar-brand" href="#">Dropdown Menu</a>
  </div>

  <div class="collapse navbar-collapse js-navbar-collapse">
    <ul class="nav navbar-nav">
      <li>...</li>
    </ul>
  </div>
</nav>

<span class="sr-only">Toggle navigation</span>

</button>

<a class="navbar-brand" href="#">Dropdown Menu</a>

</div>

</ul>

</div>

</nav>

Code pour un sous-menu qui va pousser le contenu

Le sous menu pousse le contenu vers le bas. On désolidarise la partie .navbar-header de la partie .collapse.
Attention : l’attribut data-target=".js-navbar-collapse" de <button class="navbar-toggle" /> doit avoir le même libellé que la classe sur le <div class="collapse" />.

<nav class="navbar">
    <div class="navbar-header">
    <button class="navbar-toggle" type="button" data-toggle="collapse" data-target=".js-navbar-collapse">
      <span class="sr-only">Toggle navigation</span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </button>
    <a class="navbar-brand" href="#">Dropdown Menu</a>
  </div>
</nav>
  
<nav class="navbar">
  <div class="collapse navbar-collapse js-navbar-collapse">
    <ul class="nav navbar-nav">
      <li>...</li>
    </ul>
  </div>
</nav>

<span class="sr-only">Toggle navigation</span>

</button>

<a class="navbar-brand" href="#">Dropdown Menu</a>

</div>

</nav>

</ul>

</div>

</nav>
