import reflex as rx

def index() -> rx.Component:
    return rx.center(
       form := rx.form(
            rx.vstack(
                rx.input(
                    placeholder="First Name",
                    name="first_name",
                ),
                rx.input(
                    placeholder="Last Name",
                    name="last_name",
                ),
                rx.hstack(
                    rx.checkbox("Checked", name="check"),
                    rx.switch("Switched", name="switch"),
                ),
            ),
        ),


        rx.divider(),
        rx.heading("Results"),
        rx.text(form.State.form_data.to_string()),
    )


app = rx.App()
app.add_page(index)

The above should implicitly create a submit event handler and a submit button if not specified
