成绩描写
我在创立下推菜单时碰到此毛病。我从以下地位浏览文档
这里

呼应必需在"."处包括数组。
我发明很罕见链交供给了1些处理计划，但是出有人对于我起感化

<!-- #### Setup -->
<!-- First we include `amp-bind` to track the page state and update the ``<amp-list>` data source. -->
<script async custom-element="amp-bind" src="https://cdn.ampproject.org/v0/amp-bind-0.一.js"></script>
<!-- Next we include `amp-list` to request and display the dropdowns and their options. -->
<script async custom-element="amp-list" src="https://cdn.ampproject.org/v0/amp-list-0.一.js"></script>
<!-- Finally, we include `amp-mustache` to render the mustache templates inside the `<amp-list>`s. -->
