Email Input

An email input wraps a native <input type="email"> with accessible labeling. A simpler variant of EmailAddressInput for basic email collection, it omits placeholder and autocomplete support in favor of a minimal API. Use EmailInput when you need a straightforward email field with required and disabled state support.

Example

Show demo markup 
<label class="label" for="demo-input">Label</label><input class="email-input" type="email" id="demo-input" aria-label="EmailInput" />
Usage example 
<label class="label" for="demo-input">Label</label><input class="email-input" type="email" id="demo-input" aria-label="EmailInput" />
Show Svelte source 
// In your Svelte component:
import EmailInput from "lily-design-system-svelte-headless/components/EmailInput/EmailInput.svelte";

<EmailInput label="Label" />

Usage

Contact form email field:

<EmailInput label="Email address" value={email} required />

Registration form with disabled state during submission:

<EmailInput label="Work email" value={workEmail} required disabled={isSubmitting} />

Props

  • label: string (required) -- accessible name via aria-label
  • value: string (default: "") -- current email value, two-way bindable via value
  • required: boolean (default: false) -- whether the field is required
  • disabled: boolean (default: false) -- whether the field is disabled
  • ...restProps: unknown -- additional attributes spread onto the <input>

Keyboard Interactions

None -- keyboard behavior is provided by the browser-native email input.

ARIA

  • aria-label="..." -- provides an accessible name for the email input since it has no visible <label> element

When to Use

  • Use for entering an email address with the correct mobile keyboard and browser validation.
  • Use with autocomplete="email" for faster form completion.
  • Use when browser-native email validation is sufficient for your needs.
  • Use in contact forms, registration flows, and profile editors.

When Not to Use

  • Do not use for general text input -- use TextInput instead.
  • Do not use for displaying an email as a clickable link -- use EmailLink instead.
  • Do not use when you need placeholder text or autocomplete support; consider a more feature-rich email input variant.

Headless

This headless component provides a native <input type="email"> with accessible labeling via aria-label, two-way value binding, and support for required and disabled states. Browser-native email validation is included automatically. The consumer provides all visual styling, layout, and any custom validation messages.

Styles

The consumer provides all CSS styling. The component renders with a .email-input class for targeting. No default styles are included — this is a fully headless component.

Testing

  • Verify the component renders a <input> element with class email-input
  • Verify aria-label="..." -- provides an accessible name for the email input since it has no visible <label>` element
  • Verify pass-through attributes are applied

Advice

  • Designers: Place the email input near related contact fields. Provide clear error styling when validation fails so users know the expected format.
  • Developers: Rely on the browser's built-in email validation for basic format checking. Add server-side validation for stricter requirements. Pair with a Field component for label and error message display.

Implementation Notes

  • Renders a native <input type="email"> element for browser-native email validation
  • Supports two-way binding of the email string
  • Provides aria-label for screen reader accessibility
  • Supports required and disabled for standard form behavior
  • Spreads restProps for consumer customization
  • Unlike EmailAddressInput, does not set autocomplete or support placeholder
