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()
