This page describes a Forge preview feature. Preview features are deemed stable; however, they remain under active development and may be subject to shorter deprecation windows. Preview features are suitable for early adopters in production environments.

We release preview features so partners and developers can study, test, and integrate them prior to General Availability (GA). For more information, see Forge release phases: EAP, Preview, and GA.

const App = () => {
  const [isOpen, setOpen] = useState(false);
  return (
    <Fragment>
      <Button onClick={() => setOpen(true)}>Show modal</Button>
      {isOpen && (
        <ModalDialog header="My modal dialog" onClose={() => setOpen(false)}>
          <Text>Hello there!</Text>
        </ModalDialog>
      )}
    </Fragment>
  );
};

The example app below demonstrates how to use the Form and ModalDialog components to prompt the user for information.

const App = () => {
  const [isOpen, setOpen] = useState(false);
  const [size, setSize] = useState("medium");
  return (
    <Fragment>
      <Button onClick={() => setOpen(true)}>Show modal</Button>
      {isOpen && (
        <ModalDialog header="My modal dialog" onClose={() => setOpen(false)}>
          <Form
            onSubmit={(data) => {
              setSize(data.size);
              setOpen(false);
            }}
          >
            <Select label="T-shirt size" name="size">
              <Option label="Small" value="small" />
              <Option label="Medium" value="medium" />
              <Option label="Large" value="large" />
            </Select>
          </Form>
        </ModalDialog>
      )}
    </Fragment>
  );
};
