Switch

A toggle switch alternative to the checkbox.

Sync Settings

rx.flex(
    rx.switch(default_checked=True),
    rx.text("Sync Settings"),
    spacing="2",
)

Here we set the default_checked prop to be True which sets the state of the switch when it is initially rendered.

The name of the switch is needed to submit with its owning form as part of a name/value pair.

When the required prop is True, it indicates that the user must check the switch before the owning form can be submitted.

The value prop is only used for form submission, use the checked prop to control state of the switch.

def form_switch():
    return rx.vstack(
        rx.form.root(
            rx.vstack(
                rx.switch(name="s1"),
                rx.switch(name="s2"),
                rx.switch(name="s3", required=True),
                rx.button("Submit", type="submit"),
                width="100%",
            ),
            on_submit=FormSwitchState.handle_submit,
            reset_on_submit=True,
            width="100%",
        ),
        rx.divider(),
        rx.heading("Results"),
        rx.text(FormSwitchState.form_data.to_string()),
        width="100%",
    )

The checked prop is used to control the state of the switch.

The event on_change is called when the state of the switch changes, when the change_checked event handler is called.

The disabled prop when True, prevents the user from interacting with the switch.

In our example below, even though the third switch is disabled we are still able to change whether it is checked or not using the checked prop.

class SwitchState2(rx.State):
    checked = True

    def change_checked(self, checked: bool):
        """Change the switch checked var."""
        self.checked = checked


def switch_example2():
    return rx.hstack(
        rx.switch(
            checked=SwitchState2.checked,
            on_change=SwitchState2.change_checked,
        ),
        rx.switch(
            checked=~SwitchState2.checked,
            on_change=lambda v: SwitchState2.change_checked(
                ~v
            ),
        ),
        rx.switch(
            checked=SwitchState2.checked,
            on_change=SwitchState2.change_checked,
            disabled=True,
        ),
    )

In this example we use the ~ operator, which is used to invert a var. To learn more check out var operators.
