向引导程序添加图标下拉菜单项 [英] Adding icons to bootstrap drop down menu items

问题描述

我试图添加一些图标到一个引导下拉菜单（见下面的小提琴）
，你可以看到图标被添加，但它将men u项向右推，该菜单项不对齐

这将工作。不幸的是，你似乎需要在背景图像上使用！important ，这通常最好尽量避免。注意，一些旧版本浏览器不支持nth-of-type。

  @import url（'http：// twitter。 github.com/bootstrap/assets/css/bootstrap.css'）; 
 
 .container {
 margin-top：10px; 
} 
 
 / *第一个菜单项* / 
。dropdown-menu li：nth-​​of-type（1）{
 background-image：url http://files.softicons.com/download/application-icons/32x32-free-design-icons-by-aha-soft/png/32/Color%20test.png）！important; 
 background-repeat：no-repeat; 
 background-size：16px 16px; 
 background-position：3px 5px; 
 padding-left：5px; 
} 
 
 / *第二个菜单项* / 
。dropdown-menu li：nth-​​of-type（2）{
 background-image：url http://files.softicons.com/download/application-icons/32x32-free-design-icons-by-aha-soft/png/32/Color%20test.png）！important; 
 background-repeat：no-repeat; 
 background-size：16px 16px; 
 background-position：3px 5px; 
 padding-left：5px; 
}

编辑：好吧，经过一番澄清，不想让文本转换。这里有一个类似的例子，左边没有padding和一个叫ok的类，你可以应用到不同的菜单项来添加复选框（或者你的图标可能是什么）：

  li.ok {
 background-image：url（http://files.softicons.com/download/application-icons/32x32-free-design- icons-by-aha-soft / png / 32 / Color％20test.png）！important; 
 background-repeat：no-repeat; 
 background-size：16px 16px; 
 background-position：3px 5px; 
}

I am trying to add some icons to a bootstrap dropdown menu ( see fiddle below ) as you can see the icon gets added, but it pushes the men u item to the right and that menu item is not aligned with the other items anymore.

What is the appropriate way to do this ?

js fiddle

<div class="pull-left">
<div class="pull-right">
    <div class="btn-group">                 
            <a class="btn btn-mini dropdown-toggle" data-toggle="dropdown" href="#">
                <span>Actions</span>
                <span class="caret"></span>
            </a>
            <ul class="dropdown-menu">
                <li><a href="#"><i class="icon-ok"></i>Item 1</a></li>
                <li><a href="#">Item 2</a></li>
                <li><a href="#">Item 3</a></li>
                <li class="divider"></li>
                <li><a href="#">Item 4</a></li>
                <li><a href="#">Item 5</a></li>

            </ul>
        </div>
</div>

解决方案

This will work. Unfortunately it seems that you need to use !important on the background-image which is usually best to try to avoid. Note, nth-of-type is not supported in some older browsers.

@import url('http://twitter.github.com/bootstrap/assets/css/bootstrap.css');

.container {
    margin-top: 10px;
}

/* First Menu Item */
.dropdown-menu li:nth-of-type(1) { 
    background-image: url("http://files.softicons.com/download/application-icons/32x32-free-design-icons-by-aha-soft/png/32/Color%20test.png") !important; 
    background-repeat: no-repeat;
    background-size: 16px 16px;
    background-position: 3px 5px;
    padding-left: 5px;
}

/* Second Menu Item */
.dropdown-menu li:nth-of-type(2) { 
    background-image: url("http://files.softicons.com/download/application-icons/32x32-free-design-icons-by-aha-soft/png/32/Color%20test.png") !important; 
    background-repeat: no-repeat;
    background-size: 16px 16px;
    background-position: 3px 5px;
    padding-left: 5px;
}

EDIT: Ok, after a little clarification it turns out you don't want the text shifting over at all. Here is a similar example with no padding on the left and a class called 'ok' that you can apply to different menu items to add the checkbox (or whatever your icon might be):

li.ok { 
    background-image: url("http://files.softicons.com/download/application-icons/32x32-free-design-icons-by-aha-soft/png/32/Color%20test.png") !important; 
    background-repeat: no-repeat;
    background-size: 16px 16px;
    background-position: 3px 5px;
}
