Use text input to gather free-form text from a user.

Elements

Text input elements
  1. Label: Indicates what you want the user to input in the text field.
  2. Input field: Area for user to type in their text input.
  3. Help: Provides contextual assistance like popovers, placeholder text, or helper text, in any area where the user might need additional information to provide the right input.
  4. Errors and validation: Ensures that the correct information is collected before the form can be submitted to the system.

Usage

  • Be sure to size input fields appropriately to anticipate the longest likely value (if a maximum character length is known).
  • When a value is too long to be fully displayed in a text field, use truncation.
  • Provide a text area for input anticipated to be longer than a single line.
  • Pre-populate fields with known values when possible, like a default IP address, for example.

Help

Placeholder text

Placeholder text is text inside a form field that provides an example of the required or recommended format for text input. For example, placeholder text for a date might be "DD/MM/YYYY".

Helper text

Helper text is text below a form field that helps a user provide the right information, like "Enter a unique name".

Popovers

Popovers provide context around a text or input field. Popovers are represented with an unfilled question mark con (fa-question-circle) and displayed when the user clicks on the icon.

For more information about how to provide help content, see the forms design guidelines.

Errors and validation

Wherever possible, use inline errors to notify users where there is an issue with their input. Inline errors help should be short and help users quickly identify and understand what they need to fix and why.
