Switch

The Switch component allows users to toggle between two different states. You can set a specific initial value using the defaultValue prop for an uncontrolled switch or setting the initial value of the state of a controlled switch accordingly. The name prop also needs to be specified for identifying the Switch when submitting it in a form.

OverviewPropertiesUsage

Import

import { Switch } from '@dynatrace/strato-components-preview/forms';

Use cases

CodeSandbox

Control the state

The Switch can also be controlled, meaning that you can handle the state. To do so, you need to use the onChange prop to provide a handler that is called when the internal state of the Switch changes. You also need to assign the value from the state to the Switch by setting the on prop.

CodeSandbox

Validate

This example shows how you can validate the Switch using the react-hook-form package, which handles error messages. For connecting the form with the Switch and validating, you need to register the field with custom error messages and use the useForm hook from react-hook-form. Also, by using the controlState prop, you can override the error messages and connect the Switch's error state and message to that of the form. This shows a hint in case of an error and applies proper styling to the component.
