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.
Import
import { Switch } from '@dynatrace/strato-components-preview/forms';
Use cases
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.
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.
