到我的自定义导航栏的底部。怎么会添加这样的东西？有没有将它添加到导航栏的CSS而不是将其作为图像拉入？像http://jsfiddle.net/henry12345/6h3Lee0e/

这样的东西

主要在这里：

node.prepend_child span_node

Answer 1

你可以做点什么

background:url('image_url');
background-repeat: no-repeat;
background-position: bottom center;
padding-bottom: 10px;
margin:  10px 0px  10px 0px;

或使用边框图片（http://caniuse.com/#feat=border-image IE可能是一个isssue），如果你可以提供你的html / stles - 可以建议一个解决方案

Answer 2

尝试使用水平规则和字体组合的组合。将中间的图标更改为您想要的任何内容。

Answer 3

$docInput.val(null).trigger('change.select2'); with：after property

我不知道导航栏的外观，但您可以通过在菜单<div>中添加:after属性来获得所需的效果。

以下是使用您的图片的示例：

＆＃13;

＆＃13;

<div>

＆＃13;

.menu {
    position: relative;
}

.menu:after {
    content: url(http://forrester-park.co.uk/wp-content/uploads/2014/05/Fancy-line.png);
    display: block;
    background: white;

    position: absolute;
}

＆＃13;
