twitter-bootstrap – Twitter Bootstrap 3：右对齐的折叠导航问

我有一个固定的导航栏,菜单项向右对齐,在navbar-collapse div的ul内添加.pull-right.

当导航在小屏幕上崩溃,并单击打开它,导航项目不应该是100％的宽度,而是大约30％,并向右拉.

已经解决了：

@media (max-width: 767px) { 
    .navbar-nav.pull-right { float: none!important; }
}

但是想知道是否有更好的方式来做.

导航栏的代码是：

<!-- Fixed navbar -->
<div class="navbar navbar-fixed-top">
    <div class="container">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
            <a class="navbar-brand" href="/">
                <img src="application/assets/img/main-logo.png" alt="">
            </a>
        </div>
        <div class="collapse navbar-collapse">
            <ul class="nav navbar-nav pull-right">
                <li class="active"><a href="#">Menu 1</a></li>
                <li><a href="#about">Menu 2</a></li>
                <li class="dropdown">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown">Menu 3 <b class="caret"></b></a>
                    <ul class="dropdown-menu">
                        <li><a href="#">Action</a></li>
                        <li><a href="#">Another action</a></li>
                        <li><a href="#">Something else here</a></li>
                        <li class="divider"></li>
                        <li class="dropdown-header">Nav header</li>
                        <li><a href="#">Separated link</a></li>
                        <li><a href="#">One more separated link</a></li>
                    </ul>
                </li>
                <li class="dropdown">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown">Menu 4 <b class="caret"></b></a>
                    <ul class="dropdown-menu">
                        <li><a href="#">Action</a></li>
                        <li><a href="#">Another action</a></li>
                        <li><a href="#">Something else here</a></li>
                        <li class="divider"></li>
                        <li class="dropdown-header">Nav header</li>
                        <li><a href="#">Separated link</a></li>
                        <li><a href="#">One more separated link</a></li>
                    </ul>
                </li>
                <li><a href="#about">Menu 5</a></li>
            </ul>
        </div><!--/.nav-collapse -->
    </div>
</div>
