Add your select HTML

<div id="select-theme" class="select" data-placeholder="Theme">
  <button type="button" class="w-[180px]" id="select-theme-trigger" aria-haspopup="listbox" aria-expanded="false" aria-controls="select-theme-listbox">
    <span class="truncate">Theme</span>

  </button>
  <div id="select-theme-popover" data-popover aria-hidden="true">
    <div role="listbox" id="select-theme-listbox" aria-orientation="vertical" aria-labelledby="select-theme-trigger">
      <div role="option" data-value="light">Light</div>
      <div role="option" data-value="dark">Dark</div>
      <div role="option" data-value="system">System</div>
    </div>
  </div>
  <input type="hidden" name="theme" value="" />
</div>

HTML 结构

<div class="select">

Select root. Add data-placeholder to show placeholder text when no value is selected. Supports data-close-on-select="true" for multiple select and data-format="object" for serialized object values.

<button type="button">

Trigger button. Use aria-haspopup="listbox", aria-expanded, and aria-controls.

<div data-popover aria-hidden="true">

Popover content. Supports data-side and data-align through the shared Popover rules.

<div role="listbox">

Options container. Add aria-multiselectable="true" for multiple selection.

<div role="option" data-value="..." data-label="...">: Selectable option. data-value is submitted. data-label is optional and controls the selected display label and data-format="object" label; when omitted, A3S UI uses trimmed text content.
<hr role="separator"> Optional: Separator between groups or options.
<div role="group"> Optional: Option group. Use aria-labelledby to connect it to its heading.
<span role="heading"> Optional: Group heading.

<input type="hidden">

Submitted value. Empty value means no selection when the root has data-placeholder. Single select stores a string; multiple select stores a JSON array. With data-format="object", values are serialized as { value, label } objects.

JavaScript API

应用程序编程接口	类型	描述
`change`	活动	在 `event.detail.value` 和 `event.detail.selected` 的选择发生更改时调度。
`select.refresh()`	方法	在现有 `role="listbox"` 元素内的子项发生更改后重新扫描选项。
