TextField

This is your go-to component when you need to let users input textual information.

Anchor to textfieldpropsTextFieldProps

Anchor to label label string required: Content to use as the field label.
Anchor to autocomplete autocomplete | AutocompleteField | `${} ${AutocompleteField}` | `${} ${AutocompleteField}` | `${} ${} ${AutocompleteField}` | boolean: A hint as to the intended content of the field.

When set to true, this property indicates that the field should support autofill, but you do not have any more semantic information on the intended contents.

When set to false, you are indicating that this field contains sensitive information, or contents that are never saved, like one-time codes.

Alternatively, you can provide value which describes the specific data you would like to be entered into this field during autofill.
Anchor to defaultValue defaultValue string | string[]: A default value to populate for uncontrolled components.
Anchor to disabled disabled boolean: Whether the field can be modified.
Anchor to error error string: Indicate an error to the user. The field will be given a specific stylistic treatment to communicate problems that have to be resolved immediately.
Anchor to id id string: A unique identifier for the field.
Anchor to maxLength maxLength number: Specifies the maximum number of characters allowed.
Anchor to minLength minLength number: Specifies the min number of characters allowed.
Anchor to name name string: An identifier for the field that is unique within the nearest containing Form component.
Anchor to onBlur onBlur () => void: Callback when focus is removed.
Anchor to onChange onChange (value: string) => void: Callback when the user has finished editing a field. Unlike onChange callbacks you may be familiar with from React component libraries, this callback is not run on every change to the input. Text fields are “partially controlled” components, which means that while the user edits the field, its state is controlled by the component. Once the user has signalled that they have finished editing the field (typically, by blurring the field), onChange is called if the input actually changed from the most recent value property. At that point, you are expected to store this “committed value” in state, and reflect it in the text field’s value property.

This state management model is important given how UI Extensions are rendered. UI Extension components run on a separate thread from the UI, so they can’t respond to input synchronously. A pattern popularized by controlled React components is to have the component be the source of truth for the input value, and update the value on every user input. The delay in responding to events from a UI extension is only a few milliseconds, but attempting to strictly store state with this delay can cause issues if a user types quickly, or if the user is using a lower-powered device. Having the UI thread take ownership for “in progress” input, and only synchronizing when the user is finished with a field, avoids this risk.

It can still sometimes be useful to be notified when the user makes any input in the field. If you need this capability, you can use the onInput prop. However, never use that property to create tightly controlled state for the value.

This callback is called with the current value of the field. If the value of a field is the same as the current value prop provided to the field, the onChange callback will not be run.
Anchor to onFocus onFocus () => void: Callback when input is focused.
Anchor to onInput onInput (value: string) => void: Callback when the user makes any changes in the field. As noted in the documentation for onChange, you must not use this to update value — use the onChange callback for that purpose. Use the onInput prop when you need to do something as soon as the user makes a change, like clearing validation errors that apply to the field as soon as the user begins making the necessary adjustments.

This callback is called with the current value of the field.
Anchor to placeholder placeholder string: A short hint that describes the expected value of the field.
Anchor to readOnly readOnly boolean: Whether the field is read-only.
Anchor to required required boolean: Whether the field needs a value. This requirement adds semantic value to the field, but it will not cause an error to appear automatically. If you want to present an error when this field is empty, you can do so with the error prop.
Anchor to suffix suffix string Default: '': A value to be displayed immediately after the editable portion of the field.

This is useful for displaying an implied part of the value, such as "@shopify.com", or "%".

This cannot be edited by the user, and it isn't included in the value of the field.

It may not be displayed until the user has interacted with the input. For example, an inline label may take the place of the suffix until the user focuses the input.
Anchor to value value T: The current value for the field. If omitted, the field will be empty. You should update this value in response to the onChange callback.

AutocompleteSection

The “section” scopes the autocomplete data that should be inserted to a specific area of the page. Commonly used when there are multiple fields with the same autocomplete needs in the same page. For example: 2 shipping address forms in the same page.

`section-${string}`

AutocompleteGroup

The contact information group the autocomplete data should be sourced from.

'shipping' | 'billing'
