Question

我正在使用select2使用多重选择选项（药盒）。使用上面的代码只是给了我一个基本的下拉框。问：我无法找到用户可以输入的搜索框。感谢您抽出宝贵的时间查询我的查询！这是代码。

请尝试以下操作，我认为您需要将jQuery脚本标签放置在select2之前。而且我认为您需要使用更新版本的jQuery。

<html>
<head>
    <title>multiple select</title>
    <script src="https://code.jquery.com/jquery-3.4.0.js"></script>
    <link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.6-rc.0/css/select2.min.css" rel="stylesheet" />
    <script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.6-rc.0/js/select2.min.js"></script>
</head>

<body>
<p>Multiple select example</p>
<div class="selectRow">
    <!--     Using data-placeholder below to set place holder value versus putting in configuration-->
    <select class="" id="multipleSelectExample" data-placeholder="Select an option" multiple="">
        <option value="1">Option 1</option>
        <option value="2">Option 2</option>
        <option value="3">Option 3</option>
        <option value="4">Option 4</option>
        <option value="5">Option 5</option>
    </select>
</div>
</body>
<script>
    $(document).ready(
        function () {
            $('#multipleSelectExample').select2();
        }
    );
</script>
