我正在尝试使用Dreamweaver CS6预览在html文件中创建引导选择列表。我有下面的代码应该可以工作，但是它并没有像应该的那样显示选择框-当您选择一个项目时，该项目旁边会出现一个勾号。框的外观也与http://silviomoreto.github.io/bootstrap-select/上的示例不同。

最佳答案
我看不到您的代码有任何问题。这是一个工作的小提琴：
http://jsfiddle.net/cuovoqzw/
HTML：
<h1>Hello, world!</h1>
<span class="label label-default">Default</span>
<select class="selectpicker" multiple data-selected-text-format="count>3">
<option>Mustard</option>
<option>Ketchup</option>
<option>Relish</option>
<option>Onions</option>
</select>
<form action="welcome.php" method="POST">
Name: <input type="text" name="name">
<br />
E-mail: <input type="email" name="email">
<br />
<input type="submit">
</form>
JS：
$('.selectpicker').selectpicker();
我看到的最可能的原因是，您的代码中包含了多个Bootstrap CSS文件实例。仅包括所需的内容，然后删除其余的内容。
