Forms

Input

A neutral text control with clear placeholder, focus, and icon handling.
Live example
import { Input } from "@hyzrui/core";
 
export function Example() {
  return <Input placeholder="Name" />;
}

Installation

Install the primitive source, then keep editing it inside your app. The command names the component file you want copied.

Command
pnpm dlx hyzrui add input

Usage

Import the component from the generated source folder and compose it with normal React props.

Import
import { Input } from "@hyzrui/core";
Usage
<Input className="my-input" />

Customization

Every primitive accepts local props and class names, then inherits design tokens from HyzrThemeProvider . Copy the file, keep the markup, and tune the CSS until it matches your product.

Radius--hui-radiusControls the default corner system for buttons, inputs, cards, overlays, and nested surfaces.
Foreground--hui-foregroundControls the page and component text colors. Dark mode uses the same component source with different tokens.
Surface--hui-surfaceControls card, dialog, popover, and input surfaces.
Border--hui-borderControls separators, input strokes, card outlines, and menu edges.
Primary--hui-primaryControls the main action color and the matching foreground color for solid controls.
Font--hui-font-familyControls the font stack used by every primitive inside the provider.
Control size--hui-control-font-sizeControls the default font size for buttons, inputs, selects, tabs, command rows, and menu triggers.
Control weight--hui-font-weight-controlControls the default weight of buttons, tabs, menus, badges, and compact actions.
Control height--hui-control-heightControls the default field and trigger height across forms and navigation.
Button height--hui-button-heightControls button height independently from form fields.
Button padding--hui-button-paddingControls horizontal button spacing without changing the text size.
Card padding--hui-card-paddingControls card, dialog, sheet, drawer, and panel interior spacing.
Border width--hui-border-widthControls default edge width for controls, cards, tables, and floating panels.
Focus width--hui-focus-widthControls keyboard focus outline thickness.
Motion duration--hui-transition-durationControls shared hover timing for controls and surfaces.
Hover lift--hui-hover-liftControls subtle hover lift for raised styles.
Overlay--hui-overlayControls dialog, sheet, drawer, and command overlay strength.
Floating offset--hui-floating-offsetControls menu, command, popover, and hover-card distance from the trigger.
Source fileEdit src/lib/hyzrui/components/input.tsx directly once the primitive is installed in your app.
Local classTarget .hui-input for local refinements that should not become global theme tokens.
Theme tokens
import { defineHyzrTheme } from "@hyzrui/core";
 
export const theme = defineHyzrTheme({
  id: "product",
  density: "comfortable",
  radius: 10,
  shadow: 0.08,
  colors: {
    background: "#fbfbfc",
    foreground: "#09090b",
    surface: "#ffffff",
    border: "#e4e4e7",

    primaryForeground: "#ffffff",
  },
  typography: {
    controlSize: 14,
    controlWeight: 500,
    headingWeight: 680,
  },
  sizing: {
    controlHeight: 38,
    buttonHeight: 34,
    buttonPadding: 14,
    cardPadding: 18,
  },
  borders: {
    radius: 10,
    radiusSm: 7,
    radiusLg: 16,
    width: 1,
    focusWidth: 2,
  },
  motion: {
    duration: 150,
    hoverLift: 0,
    hoverMix: 5,
  },
});

Examples

These examples show the same primitive in realistic combinations and states.

With icons

Leading icons help users identify the field purpose quickly; trailing icons add secondary affordances.

With icons
import { Mail, Search, Eye, Lock } from "lucide-react";
import { Input } from "@hyzrui/core";
 
export function InputWithIcons() {
  return (
    <div style={{ display: "grid", gap: 10, maxWidth: 320 }}>
      <Input leadingIcon={<Mail size={16} />} placeholder="Email address" />
      <Input leadingIcon={<Search size={16} />} placeholder="Search components..." />
      <Input leadingIcon={<Lock size={16} />} trailingIcon={<Eye size={16} />} placeholder="Password" type="password" />
    </div>
  );
}

Validation states

Use Field's hint for guidance before interaction and error for inline validation feedback.

Only letters, numbers, and underscores.

Validation states
import { Input, Field } from "@hyzrui/core";
 
export function InputValidation() {
  return (
    <div style={{ display: "grid", gap: 14, maxWidth: 320 }}>
      <Field label="Username" hint="Only letters, numbers, and underscores.">
        <Input defaultValue="hyzr1" />
      </Field>
      <Field label="Email" error="This email is already registered.">
        <Input defaultValue="taken@example.com" className="input-error" />
      </Field>
    </div>
  );
}

Input groups

InputGroup adds text add-ons without breaking the field's visual alignment.

      <Field label="Transfer amount">
        <InputGroup leading="$" trailing="USD">

      <Field label="Domain">
        <InputGroup leading="https://" trailing=".com">
