symfony2 knpmenu 无法下拉

Question

我正在尝试使用 knpmenu 为我的网站创建下拉导航菜单。

base.html.twig

// src/AppBundle/Menu/Builder.php
namespace AppBundle\Menu;

use Knp\Menu\FactoryInterface;
use Symfony\Component\DependencyInjection\ContainerAware;

class Builder extends ContainerAware
{
    public function topMenu(FactoryInterface $factory)
    {
        $menu = $factory->createItem('root');
        $menu->addChild('Home',array('route' => 'app'));
        $menu->addChild('Login',array('route' => 'login'));
        $menu->addChild('Register',array('route' => 'register'));

        // ... add more children

        return $menu;
    }

    public function sideMenu(FactoryInterface $factory)
    {
        $menu = $factory->createItem('root');

        $menu->setChildrenAttribute('class', 'nav pull-right');
        $menu->addChild('Leave')->setAttribute('dropdown', true);
        $menu['Leave']->addChild('Edit profile', array('route' => 'leave_app'));


        // ... add more children

        return $menu;
    }

    public function logoutMenu(FactoryInterface $factory)
    {        
        $menu = $factory->createItem('root');
        $menu->addChild('Home',array('route' => 'app'));
        $menu->addChild('Leave')->setAttribute('dropdown', true);
        $menu['Leave']->addChild('Edit profile', array('route' => 'leave_app'));      
        $menu->addChild('Claim')->setAttribute('dropdown', true);
        return $menu;
    }
}

我想为 logoutMenu 创建一个下拉列表但失败了。下拉菜单不起作用。

渲染后的 HTML 看起来也很奇怪。我不知道哪里出了问题。请帮忙。

<ul class="navigation">
    <div class="navbar navbar-fixed-top">
        <div class="navbar-inner">
            <ul>
                <li class="current first">        
                  <a href="/intra/web/app_dev.php/">Home</a>        
                </li>

                <li dropdown="dropdown">       
                <span>Leave</span>              
                <ul class="menu_level_1">
                <li class="first last">        
                    <a href="/intra/web/app_dev.php/leave">Edit profile</a>        
                </li>
                </ul>
                </li>
                    <li dropdown="dropdown" class="last">        
                    <span>Claim</span>        
                </li>
            </ul>
        </div>
    </div>
    <div class="content" style="margin-top: 50px;">
    </div>   
</ul>

我找到了解决问题的方法。正如约书亚提到的那样，可能缺少某些东西。所以怀疑 Bootstrap 有问题。我已将 Mopa Bootstrap Bundle 添加到我的项目中，并按照下面 link:

中提供的指南调用我的下拉菜单

bootstrap.mohrenweiserpartner.de/mopa/bootstrap/navbar

不知何故，下拉菜单现在可以正常工作了。
