Question

我正在通过搜索输入查找某种选择。我用materializecss构建了我的页面，但是这个库确实不支持这种类型的选择。这是我需要的最好例子 - https://material.angularjs.org/latest/demo/select#select-header。有人可以帮帮我吗？

您可以使用Select2 GitHub问题中所述的this添加搜索功能。您所需要做的就是：

将Select2样式表和javascript文件（包括jQuery）添加到您的页面。
添加额外的CSS，使Select2看起来更像是materializecss。
运行javascript代码以初始化select元素上的Select2。

$('select').select2({width: "100%"});
