Specialized text fields are available for different scenarios:

  • If you want a text field with type="search", use the SearchField component.
  • If you want a text field that shows/hides a password, use the PasswordField component.

Usage

Disabled

A text field in a disabled state shows that an input field exists, but is not available in that circumstance. This can be used to maintain layout continuity and communicate that a field may become available later.

ReadOnly

The isReadOnly prop makes the text field's text content immutable. Unlike isDisabled, the text field remains focusable and the contents can still be copied. See the MDN docs for more information.

Error

A text field can be displayed in an error state to indicate that the user input is invalid.

Clearable

The isClearable prop can be set to true to display a clear button at the end of the input.

Sizes

Text fields have multiple sizes to choose from.

Labeling

If a visible label isn't specified, an aria-label must be provided to the text field for accessibility. If the field is labeled by a separate element, an aria-labelledby prop must be provided using the ID of the labeling element instead.

Description

A text field with a helper message.

Icon Prefix

An icon can be displayed at the start of the input.

Text Prefix

A short text can be displayed at the start of the input.

Character Count

A character count can be displayed at the end of the input. The character count is based on the maxLength prop. If the maxLength prop is not set, the character count will not be displayed.

Max Length Exceeded

To exceed the max length, set the allowExceedingMaxLength prop to true – default is false. When the character count is displayed, it turns red if the max length is exceeded.

Note: If allowExceedingMaxLength is set, a character count is required to be set as well.

ContextualHelp

A ContextualHelp element may be placed next to the label to provide additional information or help about a TextField.

Fluid

A text field can take the width of its container.

Debounce

The useDebounce hook can be used to debounce user input in a text field.
