Framework7 - 多选和分组选项
描述
智能选择允许通过使用multiple 和 optgroup 属性来使用多选和分组选项。
示例
以下示例演示了在 Framework7 中使用多选和分组选项：
<!DOCTYPE html>
<html>
<head>
<meta name = "viewport" content = "width = device-width, initial-scale = 1,
maximum-scale = 1, minimum-scale = 1, user-scalable = no, minimal-ui" />
<meta name = "apple-mobile-web-app-capable" content = "yes" />
<meta name = "apple-mobile-web-app-status-bar-style" content = "black" />
<title>Multiple Select and Optgroup</title>
<link rel = "stylesheet"
href = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/css/framework7.ios.min.css" />
<link rel = "stylesheet"

<script type = "text/javascript"
src = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/js/framework7.min.js"></script>
<script>
// here initialize the app
var myApp = new Framework7 ({
animateNavBackIcon:true
});
// If your using custom DOM library, then save it to $$ variable
var $$ = Dom7;
// Add the view
var mainView = myApp.addView('.view-main', {
// enable the dynamic navbar for this view
dynamicNavbar: true
});
</script>
</body>

输出
让我们执行以下步骤来查看上面给出的代码是如何工作的：
将上面给出的 HTML 代码保存为smart_select_multiple_optgroup.html 文件，并放置在服务器根目录下。
在浏览器中打开此 HTML 文件，例如 https:///smart_select_multiple_optgroup.html，即可看到以下输出。
当您点击“城市”选项时，您可以看到每个城市的多个选项，允许您为每个城市选择多个选项，并且您可以通过点击返回链接返回上一级。
