Native Select
Browser-native `<select>` with Kamod styling, chevron affordance, sizes, validation states, and RTL-friendly layout — aligned with Starwind UI patterns. Make the expected input clear before someone interacts, and keep the current value, help text and validation feedback connected. Explore the live examples, inspect their source and choose the composition that fits your interface before connecting it to your application's data.
The examples use @/components/kamod-ui/native-select in a Preact project. Follow the live result and its source together: compare supported options in the API reference, refine presentation with the component styles guide, and use shared theme tokens for consistent colors and surfaces. Preserve keyboard behavior and meaningful labels as you replace the sample content.

Installation
Import NativeSelect, NativeSelectOption, and optionally NativeSelectOptGroup from @/components/kamod-ui/native-select.
pnpm add @kamod-ch/uiThe @/components/kamod-ui/… imports in these examples refer to local source files. Configure that alias when copying source, or use the corresponding exports from @kamod-ch/ui when installing the package. Connect the global theme CSS and Tailwind source detection before your first render.
Usage
Use NativeSelect for forms that should use the platform picker on mobile. Pair with Label and aria-invalid for accessible validation. Prefer the custom Select when you need search, portals, or rich option content.
import { NativeSelect } from "@/components/kamod-ui/native-select";Choose a complete composition from the examples below; required child components and props vary by pattern.
Component examples & variants
Explore Native Select in different contexts, from the starting pattern to the compositions below. Begin with Default, then compare the examples that match your content, state and layout. These are working patterns to adapt, not a list of interchangeable variant values: check the API reference before using a prop or combining behaviors. Look at the surrounding labels, supporting text and spacing as well as the component itself.
Read the result and its implementation together. Use each showcase’s Code view to inspect imports and composition, or its Prompt view to prepare a setup or adaptation brief. Try the narrow preview and local theme controls before connecting real data, and use Reset to return an example to its initial state. Keep layout changes in class utilities where appropriate; follow the component styles guide for hierarchy and the theming guide for shared surfaces and colors. The accessibility notes explain what to preserve when making those changes.
Default
Pair with Label and id / for for a visible field name. Use required with an empty first option so the placeholder uses theme colors (invalid:text-muted-foreground) instead of faint browser styling for disabled options.
import { Label } from "@/components/kamod-ui/label";
import { NativeSelect, NativeSelectOption } from "@/components/kamod-ui/native-select";
export const Example = () => (
<div class="flex w-full min-w-0 max-w-[240px] flex-col gap-2">
<Label for="native-select-fruit">Fruit</Label>
<NativeSelect id="native-select-fruit" class="w-full" required defaultValue="">
<NativeSelectOption value="">Select a fruit</NativeSelectOption>
<NativeSelectOption value="apple">Apple</NativeSelectOption>
<NativeSelectOption value="banana">Banana</NativeSelectOption>
<NativeSelectOption value="blueberry">Blueberry</NativeSelectOption>
<NativeSelectOption value="pineapple">Pineapple</NativeSelectOption>
</NativeSelect>
</div>
);Groups
Use NativeSelectOptGroup to organize options into categories.
Disabled
Disable the whole control or individual options.
Invalid
Use aria-invalid with a visible error message for validation feedback.
Size
Use the size prop for compact or larger touch targets.
Native Select vs Select
Choose NativeSelect for platform-native pickers and simple forms. Use the custom Select component when you need search, grouped virtualized lists, or rich option UI.
Props and data
Configure Native Select using the contracts below. Read the documented options alongside the source definitions to understand which values your application supplies and which details the component owns. Start with a prop or helper, then follow its type link to inspect the declaration without leaving the page.
Props, slots and variants for this component.
TypeScript source at build time. Props inherited through HTMLAttributes, Omit or variant helpers remain references in those declarations; their fields are not flattened here. Match the reference to your installed version, and check a package’s exports before writing an import type. A type exported by a source file is not necessarily re-exported by @kamod-ch/ui.TypeScriptComponent props
? means a field can be omitted; it does not promise a fallback value. Existing documented defaults remain alongside the descriptions. For callbacks, check the argument and return types before connecting your own state or services.Native Select

Data type reference
Expand a card to inspect and copy the exact declaration. The code header identifies its repository file; follow imported or inherited types in the implementation source when you need the complete dependency chain. Required-field summaries cover fields declared directly in that type. Source-only helpers and inferred schema outputs describe the local implementation, not additional props you can pass to every component.
NativeSelectPropsNativeSelectOptGroupPropsNativeSelectOptionPropsAccessibility
Build the complete interaction, including the parts outside Native Select. The notes below distinguish the current implementation from the labels, content and behavior your application supplies. Start with the live preview, check the props and data reference, and test the finished composition with real content rather than assuming that an unchanged visual example covers every use case.
Built-in behavior and defaults
NativeSelect keeps the browser's native select interaction, platform picker and form behavior. Its chevron is decorative. The wrapper styles do not change how labels, required values or disabled options are interpreted by the browser.
Labels and relationships
Connect a visible label to the select's ID and write understandable option text. If selection is required, use required and an empty-value prompt option. Describe the expected choice and any unavailable options before the user opens the picker.
Keyboard and focus
Keep the native keyboard and touch picker available. Group related options with native optgroup where useful. Selection should update the intended field rather than unexpectedly submitting the whole form or navigating away.
States and integration details
A disabled prompt option prevents returning to the empty state; use that only when intentional. An empty-value option is not automatically an error until your validation rules require a selection. Pair invalid styling with a linked explanation.
Verify the complete interaction
Check behavior as well as markup. Work through these scenarios in the application where the component will be used. Automated checks can help find structural problems; also review the reading experience with a screen reader, keyboard focus and the actual feedback from your application.
- Open with the keyboard and with a mobile picker; confirm labels and selected text remain clear.
- Submit the initial empty choice, choose a valid value and then reset the form.
- Check long options and localized labels without relying on the collapsed control's width alone.
Recheck the result after changing theme tokens, translations or class overrides. Include text enlargement, narrow layouts and reduced-motion settings where animation is present. Inspect the component source when a behavior differs from your expectation; a role or state attribute does not implement keyboard interaction by itself.
For background, read the WAI-ARIA authoring guidance and keyboard interface guidance. These explain the patterns; verify browser and assistive-technology behavior for the implementation and audience you actually support.
Build it into your interface
Use the Native Select examples as a starting point, then review the behavior in the context of your own screen. Layout, state and content should work together.
Connect the behavior
Choose where the value lives before wiring up validation. Use the documented change callback, preserve the field name when submitting a native form, and associate help or error text with the control. A placeholder supplements a label; it does not replace one.
Copy the composition, then connect its intent. Replace sample records and callbacks with your own data flow. For options such as value, defaultValue, open or onChange, use only those documented in this component's API; different components expose different contracts.
Give each piece of state one owner. Keep a temporary selection inside the interface when nothing else needs it; lift shared values into a parent when other controls depend on them. Read the prop reference before combining controlled values with defaults. A default normally initializes a control; it is not a substitute for updating its current value.
Connect requests in an event handler or your application’s data layer, never as a side effect of rendering. Keep pending, completed and failed outcomes distinct, preserve useful input after an error, and offer a clear recovery action. If the integration subscribes to an external source, remove that subscription when its owner unmounts; cancel or ignore obsolete requests so an earlier response cannot replace newer results.
Start with the live preview, then exercise the same interaction with your actual data. The type definitions describe accepted values; they do not implement persistence, navigation or server-side validation for you. Keep those responsibilities in the application that composes the UI.
Refine the presentation
Let a parent own the surrounding spacing. Keep related elements together with gap and use semantic surface/foreground pairs so the composition follows the active theme. The wrapper below changes the surrounding layout without assuming extra props on Native Select.
import type { ComponentChildren } from "preact";
export function ExampleSurface({ children }: { children: ComponentChildren }) {
return (
<div class="grid min-w-0 gap-4 rounded-lg border border-border bg-card p-4 text-card-foreground sm:p-6">
{children}
</div>
);
}Put the chosen example inside ExampleSurface, then refine supported variants and sizes using the API above. For application-wide changes, adjust theme tokens instead of repeating fixed colors. See Component styles for hierarchy, density and focus treatments.
Review the complete interaction
- Try an empty value, a valid value and a rejected value; keep the correction visible beside the field.
- Navigate using only the keyboard and verify the label identifies the focused control.
- Check disabled and read-only behavior separately where supported; they communicate different intentions.
The preview's narrow control changes its container width. Also resize the browser when checking viewport-based Tailwind utilities such as sm: and md:, and test overlays in the full page where their portals render.
Compose a complete interface
Native Select is one part of the interaction. Choose companion components for the information or actions that still need a place on the screen. The references below are suggestions to compose deliberately, not extra dependencies you must add to every example.
Keep one source of truth for the operation and let each component communicate a different part of it. For example, waiting, no results and failure need different explanations. Avoid showing contradictory states together, and keep recovery actions close to the message that explains them.
Start with the smallest composition that explains the task. Browse the component library for individual controls or the block collections for complete layouts. Reuse shared theme tokens so these pieces feel consistent in light and dark mode.
Sources & design references
Follow Native Select from its implementation to the ideas behind your own composition. Start with the local API, explore a visual direction, then bring the result back to your app’s shared styles.
Bring it back to your app
A reference becomes useful when it fits your real content. Work through these decisions in order:
- Keep the behavior grounded. Start with the interactive examples, then connect your data and callbacks using the integration guidance. Preserve labels, keyboard access and disabled states as you change the presentation.
- Make the styling repeatable. Use the styles guide for local
classadjustments and theming documentation for shared color decisions. Keep semantic surface and foreground pairs together in both light and dark mode. - Check the complete screen. See how components combine in the block collections, then try long labels, loading states and narrow layouts in your own composition. The Theme Toggle guide helps you expose a scheme switch in the finished interface.
