您将如何使用 显示多个选定选项的结果amp-selector？

例如在下面的代码中，

如果您同时选择美国和欧洲，列表应显示：

  • 我们
  • 我们
  • 美国和欧洲
  • 欧洲
  • 欧洲
  • 澳大利亚 & 美国 & 欧洲

根据Hai Bui的回答：您可以将复选框转换为按钮

这是工作网址

代码

    <div>
        <label class="btn">
        <input type="checkbox" value="US" on="change:AMP.setState({selected:{US: event.checked, Europe: selected.Europe, Australia: selected.Australia, Asia: selected.Asia }})"/>
        <span>US</span>
        </label>
        <label class="btn">
        <input type="checkbox" value="US" on="change:AMP.setState({selected:{US: selected.US, Europe: event.checked, Australia: selected.Australia, Asia: selected.Asia }})" />
        <span>Europe</span>
        </label>
        <label class="btn">
        <input type="checkbox" value="US" on="change:AMP.setState({selected:{US: selected.US, Europe: selected.Europe, Australia: event.checked, Asia: selected.Asia }})" />
        <span>Australia</span>
        </label>
        <label class="btn">
