Text field

    A text field is an input field that merchants can type into. It has a range of options and supports several text formats including numbers.

    Examples

    Down Arrow

    Use to allow merchants to provide text input when the expected input is short. For longer input, use the auto grow or multiline options.


    Best practices

    Text fields should:

    • Be clearly labeled so it’s obvious to merchants what they should enter into the field
    • Be labeled as “Optional” when you need to request input that’s not required
    • Only ask for information that’s really needed
    • Validate input as soon as merchants have finished interacting with a field (but not before)

    Autocomplete

    The autocomplete attribute in an input field controls two types of browser behavior:

    1. Browser autofill: a feature that automatically populates form fields with previously-saved information, such as passwords, addresses, and credit card data.
    1. Browser autocomplete - a feature that displays previously submitted values for that field.
    • When this is on for a field, a user is presented a list with previously submitted values for the input

    Recommendation

    Always add an autocomplete attribute and value to inputs if the type is: color, date, datetime-local, email, month, number, password, range, search, tel, text, time, url, or week.

    Turning autofill/autocomplete off

    Even if you do not want the browser to autofill a user's information, it is recommended you still have an autocomplete attribute with the value off or nope.

    Unfortunately, not all browsers support or respect autocomplete="off". This makes things challenging. Chrome, for example, has a long outstanding bug and won't add support for off for now.

    BrowserSupport for autocomplete="off"Details
    ChromePartialIntentionally ignores off value when the user uses the browser's autofill functionality. See bug.
    SafariPartialIgnores off value for username, email and password fields.
    FirefoxPartialIgnores off value for login forms. See bug.
    EdgePartialIntentionally ignores off value when the user uses the browser's autofill functionality.

    Chrome does seem to turn autocomplete off when using the value nope (or any non valid string). However, we have seen some inconsistencies even with that support.

    Recommendation (Chrome only)

    • Turning off both autofill and browser autocomplete (previously submitted values) in Chrome
      • Use autocomplete=nope and also must have a name attribute.
    • Turning off browser autocomplete (previously submitted values) in Chrome
      • If you don't have name attribute and the field is not a typical autofill input (address, email, etc), use autocomplete=off.

    Accessibility

    See Material Design and development documentation about accessibility for Android:

    See Apple’s Human Interface Guidelines and API documentation about accessibility for iOS:

    Structure

    Screen readers convey information about text fields automatically through native HTML.

    • Use the disabled prop to add the HTML disabled attribute to the text field.
    • Use the readOnly prop to add the HTML readonly attribute to the text field.
    • If you use the type prop, then some assistive technologies adapt the software keyboard to the current task. This helps merchants with mobility, vision, and cognitive issues to enter information more easily.

    Use the id prop to provide a unique id attribute value for the text field. If you don't provide an id, then the component generates one automatically. All text fields need to have unique id values.

    Labeling

    The label prop is required to convey the purpose of the checkbox to all merchants.

    If there are separate visual cues that convey the purpose of the text field to sighted merchants, then the label can be visually hidden with the labelHidden prop.

    When you provide help text via the helpText prop or an inline error message via the error prop, the help or error content is conveyed to screen reader users with the aria-describedby attribute. This attribute causes the content to be read along with the label, either immediately or after a short delay.

    Use the placeholder prop to provide additional instructions. However, don’t rely on placeholders alone since the content isn’t always conveyed to all merchants.

    Do

    • Use the label to provide instructions critical to using the text field
    • Use help text and placeholder text to provide additional, non-critical instructions

    Don’t

    Use the placeholder to provide information that’s required to use the text field.

    Keyboard support

    Text fields have standard keyboard support.

    • Merchants who rely on the keyboard expect to move focus to each text field using the tab key (or shift + tab when tabbing backwards)
    • If the type is set to number, then merchants can use the up and down arrow keys to adjust the value typed into the field
    • Using the disabled prop will prevent the text field from receive keyboard focus or inputs
    • The readOnly prop allows focus on the text field but prevents input or editing
    • The inputMode prop can be used to bring up a relevant keyboard for merchants on mobile; it’s passed down to the input as an inputmode attribute

    Automatically focusing

    Although you can use the autoFocus prop to automatically move focus to the text field, it’s generally best to avoid focusing on fields automatically. The autoFocus prop is set to false by default and should only be used in cases where it won’t force focus to skip other controls or content of equal or greater importance.
