TextField

A text field allows a user to enter a plain text value.

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.

Anatomy

Composed Components

A TextField uses the following components.

ErrorMessage

An error message displays validation errors for a form field.

HelperMessage

A helper message component displays auxiliary text to guide users in the interface.

Label

A label is a primitive component matching Hopper's typography type scale.

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.

Fluid

A text field can take the width of its container.

Props

prefix?

An icon or text to display at the start of the input.

showCharacterCount?

True to display the number of remaining allowed characters on the right of the input. Requires a valid value in the "maxLength" prop.

Defaults to false.
isClearable?

Whether the TextField is clearable.

placeholder?

The placeholder text when the TextField is empty.

allowExceedingMaxLength?

This should only be used with the showCharacterCount prop. If true, the TextField will allow the text to go over the max length, but it will add an error look to the character count.

size?

The size of the TextField.

Defaults to md.
onClear?

Handler that is called when the clear button is pressed.

isFluid?

If true, the TextField will take all available width.

Defaults to false.
inputRef?

A ref for the HTML input element.

necessityIndicator?

Whether the required state should be shown as an asterisk or a label, which would display (Optional) on all non required field labels.

inputGroupProps?

The props for the InputGroup.

remainingCharacterCountProps?

The props for the RemainingCharacterCount.

style?

The inline style for the element. A function may be provided to compute the style based on component state.

Migration Notes

Coming from Orbiter, you should be aware of the following changes:

  • disabled has been renamed isDisabled.
  • fluid has been renamed isFluid.
  • readOnly has been renamed isReadOnly.
  • There is no longer a loading state.
  • icon prop has been renamed to prefix.
  • Button props have been removed. To add a clear button, use the isClearable prop. For a more complex use case, create your own input using InputGroup.
  • wrapperProps no longer exists.
  • validationState has been changed to isInvalid.
  • showCharacterCount has been added.
