The label is optional and can be omitted:

Custom Responsive Steps

Use JSON in the <responsive-steps> HTML attribute to specify custom responsive steps for the <vaadin-form-layout> element.

See also: responsiveSteps property in the API Reference.

Alternatively, you can customize the responsive steps by using JavaScript to set the responsiveSteps array property.

Responsive steps can optionally have labelsOnTop: true. This sets the <vaadin-form-item> labels on top of the input fields for the steps having this flag.
