Signatures

Signature onInfoButtonClick

(
  event: MouseEvent<HTMLButtonElement> | KeyboardEvent<HTMLButtonElement>
) => void

hintIcon

The hintIcon also accepts a custom color while defaulting to warning in the case above. The hintIcon does not support the size prop, and will always be rendered in the size medium.

<FieldLabel
  title={<FormattedMessage {...messages.title} />}
  hasRequiredIndicator={true}
  onInfoButtonClick={() => {}} />}
  hint={<FormattedMessage {...messages.hint} />}
- hintIcon={<WarningIcon />}
+ hintIcon={<WarningIcon color="primary" />}
  description={<FormattedMessage {...messages.description} />}
  badge={<FlatButton tone="primary" label="show" />}
  htmlFor="sampleInput"
  horizontalConstraint={7}
/>

hint vs description

Most fields will only use the description which provides more information about what the entered value will be used for.

The hint however is used to show additional information about the value the user enters. It can show the allowed characters. It can also show whether the entered value has errors (like a reference no longer existing in an attribute) when the form is loaded for the first time.

Neither of them should be used for form validation.

Dos and don'ts

Recommended to be used in vertical forms. (E.g input field below the label, and not besides).
