Bootstrap 4: le menu déroulant va à droite de l'écran

Question

Je n'arrive pas à obtenir le menu déroulant pour ne pas quitter la page. J'ai essayé quelques solutions de BS3, mais elles ne semblent pas fonctionner. Je ne sais pas si c'est à cause de ml-auto. (ignorez les déclarations if-else)

Heres le codepen

Answer 1

Bootstrap a construit dans cette déjà: Voir le Menu d'Alignement. Il suffit d'ajouter le dropdown-menu-right classe à l' dropdown-menu div.

<div class="dropdown-menu dropdown-menu-right">

Exemple:

.navbar {
  background-color: #3c763d;
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" rel="stylesheet" />

<div class="container-fluid">
  <nav class="navbar fixed-top navbar-toggleable-md navbar-inverse">

    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>

    <div id="logo">
      <a class="navbar-brand" href="#">Company</a>
    </div>

    <div class="collapse navbar-collapse" id="navbarNav">
      <ul class="navbar-nav mr-auto hidden-md-down">
        <form action="#" class="form-inline">
          <input class="form-control" id="keyword" name="keyword" :value='keyword' type="text" placeholder="Search for jobs" />
          <input class="form-control" id="location" name="location" :value='location' type="text" placeholder="Location" />
          <button class="btn btn-secondary" type="submit">Find Jobs</button>
        </form>
      </ul>

      <ul class="navbar-nav ml-auto">
        <li class="nav-item"><a href="#" class="nav-link"><strong>Post Job</strong></a>
        </li>

        <div class="hidden-lg-up">
          <li class="nav-item">
            <a href="#" class="nav-link"><strong>Register</strong></a>
          </li>
          <li class="nav-item">
            <a href="#" class="nav-link"><strong>Profile</strong></a>
          </li>
          <li class="nav-item">
            <a href="#" class="nav-link"><strong>My Jobs</strong></a>
          </li>
          <li class="nav-item">
            <a href="#" class="nav-link"><strong>My Searches</strong></a>
          </li>
          <li class="nav-item">
            <a href="#" class="nav-link"><strong>Employer Dashboard</strong></a>
          </li>
          <li class="nav-item">
            <a href="#" class="nav-link"><strong>Login</strong></a>
          </li>
          <li class="nav-item">
            <a href="#" class="nav-link"><strong>Logout</strong></a>
          </li>
        </div>

        <li class="nav-item dropdown hidden-md-down">
          <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
            <strong>Account</strong>
          </a>
          <div class="dropdown-menu dropdown-menu-right" aria-labelledby="navbarDropdownMenuLink">
            <a class="dropdown-item"><strong>Register</strong></a>
            <a href="#" class="dropdown-item"><strong>Profile</strong></a>
            <a href="#" class="dropdown-item"><strong>My Jobs</strong></a>
            <a href="#" class="dropdown-item"><strong>My Searches</strong></a>
            <a href="#" class="dropdown-item"><strong>Employer Dashboard</strong></a>
            <a href="#" class="dropdown-item"><strong>Login</strong></a>
            <a href="#" class="dropdown-item">
              <div class="dropdown-divider"></div>
              <strong>Logout</strong>
            </a>
          </div>
        </li>

      </ul>
    </div>

  </nav>
</div>

Answer 2

Pour le bénéfice de ceux qui trébuchent sur cette question lors de googler, mais sont à l'aide de réagir, a accepté de répondre (alors que correct) ne résoudra pas le problème pour vous. Réagir ignore 'dropdown-menu à droite" quand vous l'ajouter manuellement à celui de la classe. Au lieu de cela, mettez à jour votre code ci-dessous et il définit correctement la même classe.

Pour le javascript

<DropdownMenu right>

Pour tapuscrit

<DropdownMenu right={true}>

Mettre ici comme ce fil est apparu lorsque j'ai été googler le problème et m'a pris du temps à comprendre la bonne solution pour bootstrap 4 à réagir (reactstrap).
