Toggle

Toggle controls a binary pressed/unpressed state with modern Radix-style variants and sizes. Make the next action easy to recognize. Use visual emphasis deliberately and distinguish an action from a persistent selection or a navigation link. 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/toggle 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 Toggle from @/components/kamod-ui/toggle.

pnpm add @kamod-ch/ui

The @/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 variant, size, and controlled state props to match toolbar and settings use-cases.

import { Toggle } from "@/components/kamod-ui/toggle";

Choose a complete composition from the examples below; required child components and props vary by pattern.

Component examples & variants

Explore Toggle in different contexts, from the starting pattern to the compositions below. Begin with Basic Toggle, 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.

Basic Toggle

A compact default toggle with an initial pressed state.

src/components/ToggleExample.tsx

import { Toggle } from "@/components/kamod-ui/toggle";
import { Bold } from "lucide-preact";

export const Example = () => (
  <Toggle defaultPressed aria-label="Toggle bold">
    <Bold class="size-4" />
  </Toggle>
);

Toolbar Actions

Render grouped actions in a compact, modern formatting toolbar.

API reference

Props and data

Configure Toggle 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.

Type cards are extracted from this checkout’s 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.TypeScript

Component props

Read each option with its owning component. The marker identifies required fields verified in that declaration. A ? 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.

Toggle

Toggle component props and accepted values.

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.

Toggle props

ToggleProps

Exported source declaration from Toggle.tsx. Referenced types retain their original names; inspect that file for imports and supporting definitions.

Accessibility

Build the complete interaction, including the parts outside Toggle. 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

Toggle renders a button with aria-pressed reflecting its state. Pressed state represents a persistent choice, not just the brief visual feedback of clicking a normal action button.

Labels and relationships

Keep the label stable while the state changes: Bold remains Bold whether pressed or not. Give icon-only toggles an explicit name. Add a description when the effect is scoped to a selected item or part of the document.

Keyboard and focus

Enter and Space activate the button. Controlled pressed state and its callback must stay in sync with the actual application setting. A failed save should not leave an apparently enabled feature that did not take effect.

States and integration details

Do not use pressed styling for navigation to the current page; use a link and current-page semantics instead. Keep focus and pressed treatments distinguishable, and avoid communicating selection with color alone.

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.

Toggle twice using the keyboard and confirm the pressed state is announced each time.
Verify the name stays meaningful while selected, unselected and disabled.
Simulate an external state update or failed persistence and confirm the control reflects the true value.

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 Toggle 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

Use an action label that describes the result. Within a form, choose button types deliberately so a secondary action does not submit accidentally. Use the supported selected or pressed state for persistent choices, and provide an accessible name for icon-only controls.

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 Toggle.

src/components/ExampleSurface.tsx

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

Check hover, focus, pressed and disabled states using both pointer and keyboard.
For asynchronous actions, prevent duplicate submissions and show a useful pending label.
Keep the primary action recognizable when labels wrap, text is enlarged or the theme changes.

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

Toggle 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 Toggle 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.

Implementation · Preact

Kamod UI implementation

Start with the code that powers this page. The Toggle source in Kamod UI is the implementation reference. Use the installation guide for setup and the API reference for supported props, composition and events before adapting an example.

Source locationpackages/core/src/components/toggle

Compare imports, default values and state handling with the example you chose. The repository’s main branch can be ahead of your installed version; check your package.json and lockfile when an API differs. Retain applicable license notices when reusing source.

Visual reference · Independently maintained

Explore the visual possibilities

Browse the Toggle collection on Shadcnblocks to compare hierarchy, density and composition. Look at how labels, supporting text and surrounding space work together, then choose the details that help your own content read clearly.

Reference credit: Shadcnblocks. These independently maintained React examples are visual references; this link does not claim they authored Kamod’s Preact implementation. Check the original example’s license before reusing its code or assets, and use this page’s API when building the Kamod version.

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 class adjustments 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.
