Bootstrap多级导航栏(级联导航)的实现代码
在bootstrap官方来说,导航最多就是两级,两级以上是无法实现的,大叔找了一些第三方的资料,终于找到一个不错的插件,使用上和效果上都还不错,现在和大家分享一下
插件地址:http://vsn4ik.github.io/bootstrap-submenu/
先看一下,在后台系统上的显示效果
下面说一下实现的方式
1.引用三个JS插件和一个CSS类库
<script src="~/Content/bootstraps/JS/bootstrap-submenu.js"></script> <script src="~/Content/bootstraps/JS/highlight.min.js"></script> <script src="~/Content/bootstraps/JS/docs.js"></script> <link href="~/Content/bootstraps/CSS/bootstrap-submenu.css" rel="stylesheet" />
2.插入对应的HTML代码块,本例子没有使用递归生成代码,使用了静态的三级结构,这样看着更清晰,真正的生产环境建议使用递归去生产菜单
<ul class="nav nav-pills"> @foreach (var item in Model) { if (item.Sons != null && item.Sons.Count > 0) { <li class="dropdown"> <a data-submenu="" data-toggle="dropdown" tabindex="0">@item.MenuName<span class="caret"></span></a> <ul class="dropdown-menu"> @foreach (var sub in item.Sons) { if (sub.Sons != null && item.Sons.Count > 0) { <li class="dropdown-submenu"> <a tabindex="0">@sub.MenuName</a> <ul class="dropdown-menu"> @foreach (var inner in sub.Sons) { <li> <a href="@inner.LinkUrl">@inner.MenuName</a> </li> } </ul> </li> <li class="divider"></li> } else { <li><a href="@sub.LinkUrl">@sub.MenuName</a></li> } } </ul> </li> } else { <li><a href="@item.LinkUrl">@item.MenuName</a></li> } } </ul>
最后的效果就是第一个图了,值得注意的是,如果希望每个菜单之间使用分割线,可以添加 <li class="divider"></li>这行代码。
下面给大家推荐一段代码有关Bootstrap多级级联菜单
<div class="navbar navbar-fixed-top"> <div class="navbar-inner"> <div class="container-fluid"> <a data-target=".nav-collapse" data-toggle="collapse" class="btn btn-navbar"> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </a> <a href="#" class="brand">Project name</a> <div class="nav-collapse"> <ul class="nav"> <li class="active"> <a href="#">Home</a> </li> <li> <a href="#">Link</a> </li> <li> <a href="#">Link</a> </li> <li> <a href="#">Link</a> </li> <li class="dropdown"> <a data-toggle="dropdown" class="dropdown-toggle" href="#"> Dropdown <b class="caret"></b> </a> <ul class="dropdown-menu"> <li class="dropdown-submenu"> <a href="#">More options</a> <ul class="dropdown-menu"> <li> <a href="#">Second level link</a> </li> <li> <a href="#">Second level link</a> </li> <li> <a href="#">Second level link</a> </li> <li> <a href="#">Second level link</a> </li> <li class="dropdown-submenu"> <a href="#">Second level link</a> <ul class="dropdown-menu"> <li> <a href="#">3333333333</a> </li> </ul> </li> </ul> </li> <li> <a href="#">Another action</a> </li> <li> <a href="#">Something else here</a> </li> <li class="divider"></li> <li class="nav-header">Nav header</li> <li> <a href="#">Separated link</a> </li> <li> <a href="#">One more separated link</a> </li> </ul> </li> </ul> <form action="" class="navbar-search pull-left"> <input type="text" placeholder="Search" class="search-query span2"> </form> <ul class="nav pull-right"> <li> <a href="#">Link</a> </li> <li class="divider-vertical"></li> <li class="dropdown"> <a class="#" href="#">Menu</a> </li> </ul> </div><!-- /.nav-collapse --> </div> </div> </div> <hr /> <ul class="nav nav-pills"> <li class="active"> <a href="#">Regular link</a> </li> <li class="dropdown"> <a href="#" data-toggle="dropdown" class="dropdown-toggle"> Dropdown <b class="caret"></b> </a> <ul class="dropdown-menu" id="menu1"> <li class="dropdown-submenu"> <a href="#">More options</a> <ul class="dropdown-menu"> <li> <a href="#">Second level link</a> </li> <li> <a href="#">Second level link</a> </li> <li> <a href="#">Second level link</a> </li> <li> <a href="#">Second level link</a> </li> <li> <a href="#">Second level link</a> </li> </ul> </li> <li> <a href="#">Another action</a> </li> <li> <a href="#">Something else here</a> </li> <li class="divider"></li> <li> <a href="#">Separated link</a> </li> </ul> </li> <li class="dropdown"> <a href="#">Menu</a> </li> <li class="dropdown"> <a href="#">Menu</a> </li> </ul>
