#HTML 结构

<div class="combobox">

Root element. Add data-auto-highlight="true" to make the first visible option active when the list opens or filters. Add data-format="object" to serialize selected values as objects. Add data-filter="manual" when your app owns filtering.

<input type="text" role="combobox">

The editable control. It can be a direct child, inside .input-group, or inside data-popover for popup mode.

<button aria-haspopup="listbox"> Optional

Opens the list from an input group or popup trigger. In popup mode, include a child with data-value and optional data-placeholder to display the selected value.

<button data-clear> Optional

Clears the current selection. Put the clear icon inside the button.

<svg class="combobox-trigger-icon"> Optional

Decorative trailing icon for input-style comboboxes. Replace the SVG to customize the icon.

<div data-popover>

The suggestions popup. Use data-side and data-align like Popover; the shared runtime flips and clamps the list to the visual viewport.

<div role="listbox">

The suggestions list. Add aria-multiselectable="true" in multiple mode. The component uses that attribute to render selected chips around the input.

<div role="option" data-value="...">

Selectable option. Options can contain custom HTML; use data-label when the input should display different text than the rendered content.

<input type="hidden">

Submitted value. Single mode stores a string; multiple mode stores a JSON array. With data-format="object", selected values are stored as objects.
