使用 spring boot 实现 css 多个 select
materialize css multiple select with springboot
我目前正在 springboot 工作，前端使用了 materialize css，
在使用 materialize css 多个 select、运行 时，html 文件单独工作就像一个魅力，但是当我将我的 html 文件与 spring 启动，它抛出一个运行时错误，代码如下。
代码：()
<div class="input-field" multiple>
<select>
<option value="english">English</option>
<option value="tamil">Tamil</option>
</select>
<label>Materialize Multiple Select</label>
</div>
错误代码：
org.xml.sax.SAXParseException: Attribute name "multiple" associated with an element type "div" must be followed by the ' = ' character.

输出进入 运行 html 文件，没有 springboot:
除了与 springboot 相同，但以错误告终：/
任何类型的建议都会有所帮助！！
您应该将 multiple 属性添加到 <select> 标签，而不是 <div>。
请将您的 html 代码更改为：
<div class="input-field">
<select multiple>
<option value="english">English</option>
<option value="tamil">Tamil</option>
</select>
<label>Materialize Multiple Select</label>
</div>
对我不起作用，但我找到了解决方法：-} 使用 jquery 将这部分代码单独动态添加到页面，这样 eclipse 就不会在 [=12= 中抛出错误] 在运行时，无论如何感谢您的响应:)
