Question

我正在尝试创建一个垂直且最多3级导航的导航菜单，最后一级是可切换菜单（当你点击最后一级菜单时，下面会出现一组子菜单）。示例结构菜单结构与此类似

我尝试了以下代码，但未获得所需的输出

有没有办法使用bootstrap创建一个垂直的多级菜单结构，jquery我还没有任何带有垂直方向的多级菜单。使用此代码时出现css问题，无法创建类似的导航菜单。

Answer 1

这可能不是您正在寻找的答案，但它是我在您的案例中会做的。

我有时使用bootstrap但是，尽管它很好，但在我看来，人们常常认为这是一个神奇的代码，可以让你做任何你想做的事情，最近我发现人们花了更多的时间试图修改bootstrap css而不是从头开始制作整个css（如果你知道一些基本的css），不要说那么多的网站＆＃34;寻找＆＃34;所以simillar。

对于你想要做什么我基本上清除html中的所有类，只是从容器中狙击元素我可以在图像中显示一个菜单（好吧，它需要一些额外的风格，如添加箭头图标，阴影等，但重点是向您展示另一种方法）。

HTML：

<div class="container">        
            <ul class="">

                <li class="">
                    <a tabindex="-1" href="#">Client Advice</a>
                    <ul class="">

                        <li class=""><a tabindex="-1" href="#">Pre-advice</a></li>
                        <li class=""><a href="#">Strategy & Technical</a></li>
                        <li class=""><a href="#">Research</a></li>
                        <li class="">
                            <a href="#">APL & Products</a>
                            <ul class="parent">
                                <li >
                                    <a href="#">
                                        Approved Product List                                        
                                    </a>

                                    <ul class="child">
                                        <li >Platforms</li>
                                        <li >Managed Funds</li>
                                        <li >Wealth Protection</li>
                                        <li >Listed Securities</li>
                                        <li >Wealth Protection</li>
                                        <li >Listed Securities</li>
                                        <li >Listed Securities</li>
                                    </ul>

                                </li>
                                <li ><a href="#">Model Portfolios</a></li>
                                <li ><a href="#">Non-approved Products</a></li>
                            </ul>
                        </li>
                        <li class=""><a href="#">Implementation</a></li>
                        <li class=""><a href="#">Review</a></li>
                        <li class=""><a href="#">Execution Only</a></li>
                    </ul>
                </li>
                <li ><a href="#">Personal Development</a></li>
                <li ><a href="#">Practice</a></li>
                <li ><a href="#">News</a></li>
            </ul>

    </div>

只是这个css（请注意，当我直接拨打<a>标签时，您可能需要以不同的方式调用它：

html, body {
    margin:0;
    padding:0;
    height:100%;
}
* {box-sizing: border-box;}
.container {
    height:100%;
}
a {
    color:#fff;
    text-decoration:none;
    border-bottom:1px dotted #fff;
    padding:0px 0px 20px 0px;
    width:100%;
    display:block;
    height:100%;
}
li {
    padding:20px 20px 0 20px;
    width:100%;
    color:#fff;
}
.container ul {height:100%;}
.container > ul {
    width:250px;
    background-color:#224490;
    position:relative;
    overflow:visible;
}
.container > ul > li {}
.container > ul > li:hover {background-color:#0f1e41;}
.container > ul > li > ul {
    display:none;
    position:absolute;
    right:-250px;
    top:0;
    width:250px;
    background-color:#18316a;
}
.container > ul > li:hover > ul {
    display:block;
}
.container > ul > li > ul >li:hover {background-color:#0f1e41;}
.container > ul > li > ul > li > ul {
    display:none;
    position:absolute;
    right:-250px;
    top:0;
    width:250px;
    background-color:#112551;
}
.container > ul > li > ul > li:hover ul {
    display:block;
}
.container > ul > li > ul > li > ul > li:hover {background-color:#0f1e41;}
.container > ul > li > ul > li ul li ul li {
    border-bottom:1px dotted #fff;
    padding:20px;
}

我刚刚保留了激活脚本的类，所以保持不变。
