我只是想问为什么引导程序中的下拉子菜单不起作用,我只是按照此链接中的说明操作:(http://getbootstrap.com/2.3.2/components.html)但是子菜单上的下拉子菜单仍然没有出现。顺便说一句,我没有更改或覆盖CSS中的类。
这是我的代码! :)
<li class='dropdown'><a class='dropdown-toggle active' data-toggle='dropdown' href='#'><img src = 'images/forbank.png' height = 35 width = 35>Banking<span class='caret'></span></a>
<ul class='dropdown-menu'>
<li class = 'dropdown-submenu'><a tabindex='-1' href='#'><span class = 'glyphicon glyphicon-cog'> </span> Transaction</a>
<ul class='dropdown-menu' role = 'menu'>
<li><a tabindex='-1' href='#'> Withdrawal / Deposit </a></li>
<li><a tabindex='-1' href='#'> Fixed Deposit </a></li>
</ul>
</li>
<li role='separator' class='divider'></li>
<li><a href='#'><span class='glyphicon glyphicon-list-alt'> </span> Summaries </a></li>
<li><a href='#'><span class='glyphicon glyphicon-wrench'> </span> Settings </a></li>
</ul>
</li>

请确认您所遵循的说明是否与您的引导版本相符。
此外,您可以尝试包含这几行CSS以使其正常工作。
.dropdown-submenu {
position: relative;
}
.dropdown-submenu>.dropdown-menu {
top: 0;
left: 100%;
margin-top: -6px;
margin-left: -1px;
-webkit-border-radius: 0 6px 6px 6px;
-moz-border-radius: 0 6px 6px;
border-radius: 0 6px 6px 6px;
}
.dropdown-submenu:hover>.dropdown-menu {
display: block;
}
.dropdown-submenu>a:after {
display: block;
content: " ";
float: right;
width: 0;
height: 0;
border-color: transparent;
border-style: solid;
border-width: 5px 0 5px 5px;
border-left-color: #ccc;
margin-top: 5px;
margin-right: -10px;
}
.dropdown-submenu:hover>a:after {
border-left-color: #fff;
}
.dropdown-submenu.pull-left {
float: none;
}
.dropdown-submenu.pull-left>.dropdown-menu {
left: -100%;
margin-left: 10px;
-webkit-border-radius: 6px 0 6px 6px;
-moz-border-radius: 6px 0 6px 6px;
border-radius: 6px 0 6px 6px;
}

我做到了,但问题是&#34;提款/存款&#34;的子菜单。和#34;定期存款&#34;正在阻止父子菜单&#34;交易&#34;,它在悬停期间不会到达它的右侧。这是我现在的代码。
<li class='dropdown'><a id = 'dLabel' class='dropdown-toggle active' data-toggle='dropdown' href='#'><img src = 'images/forbank.png' height = 35 width = 35>Banking<span class='caret'></span></a>
<ul class='dropdown-menu multi-level' role='menu' aria-labelledby='dropdownMenu'>
<li class = 'dropdown-submenu'>
<a tabindex = '-1' href='#'><span class = 'glyphicon glyphicon-cog'> </span> Transaction </a>
<ul class='dropdown-menu'>
<li><a tabindex='-1' href='#'> Withdrawal / Deposit </a></li>
<li><a tabindex='-1' href='#'> Fixed Deposit </a></li>
</ul>
</li>
<li role='separator' class='divider'></li>
<li><a href='#'><span class='glyphicon glyphicon-list-alt'> </span> Summaries </a></li>
<li><a href='#'><span class='glyphicon glyphicon-wrench'> </span> Settings </a></li>
</ul>
</li>
