如何使用所有菜单项的容器获取全宽下拉区域

Question

你能帮我做菜单吗？

我找到了类似的链接

`http://jsfiddle.net/KyleMit/6cu8f43m/`

但它没有获得带有容器菜单项的全宽导航栏

Answer 1

在该代码中还提到了全宽子菜单项的详细信息。

选择所有礼品中的全宽。如下所示：

 <li class="dropdown full-width">
                <a href="#" class="dropdown-toggle" 
                data-toggle="dropdown">
                    Fill Width <span class="caret"></span>
                </a>
                <ul class="dropdown-menu" role="menu">
                    <li><a href="#">Action</a></li>
                    <li><a href="#">Another action</a></li>
                    <li><a href="#">Really Really Really Really Really Really Really Really Really Really Really Really Really Really Really Really Really Long
                        </a></li>
                    <li class="divider"></li>
                    <li><a href="#">Separated link</a></li>
                    <li class="divider"></li>
                    <li><a href="#">One more separated link</a></li>
                </ul>
            </li>

只需将最外层div的类更改为导航栏而不是容器。 或者更好的方法是使用<nav> </nav>代替最外层的<div class="container"> </div>
