[英]Bootstrap Dropdown menu shifting around and styling not appearing
仅编码了几个月,所以您的帮助不胜感激:)
我设计了一个带有标题的客户标头,标题浮动在左边,而号召性用语(CTA)按钮则浮动在右边,我希望将它们变成onclick的下拉菜单。 我正在借用Bootstrap的Dropdown组件。 我遇到了一些问题:
HTML:
<div id="header-container">
<div id="header-wrapper">
<div id="header-left">
<div class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">
<img src="" />
<span class="caret"></span>
</a>
<ul class="dropdown-menu">
<li><a href="#">Option 1</a></li>
<li><a href="#">Option 2</a></li>
<li><a href="#">Option 3</a></li>
<li><a href="#">Option 4</a></li>
</ul>
</div>
</div>
<div id="header-right">
<div class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">
Take Pledge
<b class="caret"></b>
</a>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Option 1</a></li>
<li><a href="#">Option 2</a></li>
<li><a href="#">Option 3</a></li>
<li><a href="#">Option 4</a></li>
</ul>
</div>
</div>
</div>
</div>

看看这个小提琴 ,我已经注释了一些样式(最大宽度等)。
变化是
<div id="header-right" class="pull-right">
#header-container {
/*overflow: auto;*/
width: 100%;
background-color: #231F20;
height: 50px;
}
#header-wrapper {
/*margin-left: auto;
margin-right: auto;
width: 80%;
min-width: 1000px;
max-width: 1300px;*/
overflow: visible;
}
#header-left {
float: left;
margin: 5px 0 0 0;
}
#header-right {
float: right;
margin: 5px 0 0 20px;
}
.dropup,
.dropdown {
position: relative;
}
.dropdown-menu {
position: absolute;
top: 100%;
left: 0;
z-index: 1000;
display: none;
float: left;
min-width: 160px;
padding: 5px 0;
margin: 2px 0 0;
list-style: none;
background-color: #ffffff;
border: 1px solid #ccc;
border: 1px solid rgba(0, 0, 0, 0.2);
*border-right-width: 2px;
*border-bottom-width: 2px;
-webkit-border-radius: 6px;
-moz-border-radius: 6px;
border-radius: 6px;
-webkit-box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
-moz-box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
-webkit-background-clip: padding-box;
-moz-background-clip: padding;
background-clip: padding-box;
}
希望这可以帮助
