css - Bootstrap 3 中的下 zipper 接水平堆叠

Question

我有多个菜单下 zipper 接。一切正常。但是当屏幕尺寸是平板电脑的尺寸时，下 zipper 接无法正确呈现。当我单击第一个下 zipper 接“成员(member)资格”时，下拉项“管理用户”和下一个下 zipper 接“站点配置”将水平并排呈现，而不是一个在另一个下方。请帮忙。

您对 pull-left 类的使用导致列表项向左浮动，从而水平堆叠。删除类，这应该可以工作。

<div class="navbar navbar-inverse 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>                        
            </div>
            <div class="navbar-collapse collapse">
                <ul class="nav navbar-nav navbar-right">
                    <li class="navbar-text">Welcome, User!</li>
                </ul>

<ul class="nav navbar-nav navbar-right">
