Native Select

Style a native select while preserving platform behavior. CSS only

<div class="ui-field">
  <label class="ui-label" for="channel">Release channel</label>
  <div data-ui-part="control">
    <select class="ui-select" id="channel" name="channel">
      <option value="preview">Preview</option>
      <option value="stable" selected>Stable</option>
    </select>

  </div>
</div>

Anatomy

Parts are authored in your own markup and identified by the selector below, so your CSS can target the same anatomy without loading Timeless styles. Required parts must be present for the component to work. Private data-ui-internal-* hooks are written by the runtime and must never be authored.

ui-field

Part	Required	Selector	Purpose
`control`	No	`[data-ui-part~='control']`	Wrapper around the native control when one is needed.

Attributes

Every value below is implemented by the stylesheets this component ships. Boolean attributes are presence-based: author the attribute with no value, or omit it.

ui-select

Attribute	Values	Default	Description
`data-ui-size`	`sm` · `md` · `lg`	`md`	Control height, padding, and font size.

ui-field

Attribute	Values	Default	Description
`data-ui-layout`	`stacked` · `inline`	`stacked`	Whether the label sits above the control or beside it.
`data-ui-density`	`compact` · `normal` · `spacious`	`normal`	Gap between label, control, description, and error.

State

Native attributes, ARIA, and platform pseudo-classes are authoritative. Style state through the selectors below rather than adding your own state classes.

State	Source	How to express it
`invalid`	native	Native `:invalid`, or `aria-invalid="true"`.
`disabled`	native	Native `disabled`.
`invalid`	aria	Set `aria-invalid="true"` on the control and point `aria-describedby` at the error part.

Styling

Root identity: ui-select, ui-field, ui-label. Required stylesheets: tokens.css, forms.css.

This component adds no custom properties of its own. Restyle it through the design tokens or your own CSS.

Design tokens this component reads (25)

These are global Atmosphere tokens. Change them once at the theme level rather than per component.

--ui-accent · --ui-bg-control · --ui-bg-control-muted · --ui-bg-surface · --ui-bg-surface-subtle · --ui-danger · --ui-danger-soft · --ui-duration-fast · --ui-ease-standard · --ui-fg · --ui-fg-muted · --ui-fg-subtle · --ui-focus · --ui-line · --ui-line-strong · --ui-radius-md · --ui-radius-pill · --ui-radius-sm · --ui-shadow-control · --ui-shadow-inset · --ui-space-1 · --ui-space-2 · --ui-space-3 · --ui-space-4 · --ui-space-5

Accessibility

Keep the native elements, roles, and relationships shown in the example. Timeless adds only the state and keyboard coordination the platform does not already provide, and it never supplies your accessible names — those depend on your content.

Before JavaScript runs

This primitive is CSS only. There is nothing to register and nothing to wait for.
