【Bootstrap 下拉菜单】
<div class="dropdown"> <button type="button" class="btn dropdown-toggle" id="dropdownMenu1" data-toggle="dropdown">主题 <span class="caret"></span> </button> <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1"> <li role="presentation"> <a role="menuitem" tabindex="-1" href="#">Java</a> </li> <li role="presentation"> <a role="menuitem" tabindex="-1" href="#">数据挖掘</a> </li> <li role="presentation"> <a role="menuitem" tabindex="-1" href="#">数据通信/网络</a> </li> <li role="presentation" class="divider"></li> <li role="presentation"> <a role="menuitem" tabindex="-1" href="#">分离的链接</a> </li> </ul> </div>
实现下拉菜单有几个要点:
1、根部div必须 class="dropdown"
2、Button必须 data-toggle="dropdown"
3、ul必须 class="dropdown-menu"
可以通过js来调用:
$('.dropdown-toggle').dropdown()
