AntDesign: Conditionally show form fields

What's the easiest way to show/hide another form field based on whether another is true or false? If Field A is true, Field B should be visible. If Field B is false, Field B should have it's value set to null and be hidden.
const { formLoading, formProps, onFinish, saveButtonProps, queryResult } = useForm<IOnboardingChecklist>({
resource: 'onboarding_checklist',
id: userID,
redirect: false,
warnWhenUnsavedChanges: false,
});
<Form
{...formProps}
layout='vertical'
>
<Row>
<Col span={8}>
<Form.Item label='User has LinkedIn account' name='has_linkedin_account'>
<Switch />
</Form.Item>
</Col>
{
// TODO: Conditionally show this if has_linkedin_account is true
}
<Col span={8}>
<Form.Item label='LinkedIn archiving completed' name='linkedin_archiving'>
<Switch />
</Form.Item>
</Col>
</Row>
</Form>
const { formLoading, formProps, onFinish, saveButtonProps, queryResult } = useForm<IOnboardingChecklist>({
resource: 'onboarding_checklist',
id: userID,
redirect: false,
warnWhenUnsavedChanges: false,
});
<Form
{...formProps}
layout='vertical'
>
<Row>
<Col span={8}>
<Form.Item label='User has LinkedIn account' name='has_linkedin_account'>
<Switch />
</Form.Item>
</Col>
{
// TODO: Conditionally show this if has_linkedin_account is true
}
<Col span={8}>
<Form.Item label='LinkedIn archiving completed' name='linkedin_archiving'>
<Switch />
</Form.Item>
</Col>
</Row>
</Form>

Hi @James. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- You can achieve this by using the getFieldValue method from Ant Design's Form instance to get the value of the 'has_linkedin_account' field. Then, you can conditionally render the 'linkedin_archiving' field based on this value. Here's how you can do it:
const { formLoading, formProps, onFinish, saveButtonProps, queryResult } = useForm<IOnboardingChecklist>({
resource: 'onboarding_checklist',
id: userID,
redirect: false,
warnWhenUnsavedChanges: false,
});

<Form
{...formProps}
layout='vertical'
>
<Row>
<Col span={8}>
<Form.Item label='User has LinkedIn account' name='has_linkedin_account'>
<Switch />
</Form.Item>
</Col>
{
formProps.form.getFieldValue('has_linkedin_account') && (
<Col span={8}>
<Form.Item label='LinkedIn archiving completed' name='linkedin_archiving'>
<Switch />
</Form.Item>
</Col>
)
}
</Row>
</Form>
const { formLoading, formProps, onFinish, saveButtonProps, queryResult } = useForm<IOnboardingChecklist>({
resource: 'onboarding_checklist',
id: userID,
redirect: false,
warnWhenUnsavedChanges: false,
});

<Form
{...formProps}
layout='vertical'
>
<Row>
<Col span={8}>
<Form.Item label='User has LinkedIn account' name='has_linkedin_account'>
<Switch />
</Form.Item>
</Col>
{
formProps.form.getFieldValue('has_linkedin_account') && (
<Col span={8}>
<Form.Item label='LinkedIn archiving completed' name='linkedin_archiving'>
<Switch />
</Form.Item>
</Col>
)
}
</Row>
</Form>
In this code, formProps.form.getFieldValue('has_linkedin_account') will return the value of the 'has_linkedin_account' field. If this value is true, the 'linkedin_archiving' field will be rendered. If it's false, the 'linkedin_archiving' field will not be rendered. Please note that this will only hide the 'linkedin_archiving' field from the UI. If you want to also set its value to null when 'has_linkedin_account' is false, you can use the setFieldsValue method:
if (!formProps.form.getFieldValue('has_linkedin_account')) {
formProps.form.setFieldsValue({ linkedin_archiving: null });
}
if (!formProps.form.getFieldValue('has_linkedin_account')) {
formProps.form.setFieldsValue({ linkedin_archiving: null });
}
This code should be placed in a useEffect hook that depends on the value of 'has_linkedin_account', so it runs whenever this value changes. For more information, refer to the Ant Design Form (https://ant.design/components/form/) documentation and the Refine's useForm hook (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-form/) documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Is there a way to do a live update of the field when the value is changed? Currently it requires a form reload.

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, Refine provides a liveMode property in its useForm hook that can be used to update data in real-time throughout your app. You can set liveMode to "auto" to update data automatically if a related live event is received. Here's how you can use it:
useForm({
refineCoreProps: {
liveMode: "auto",
},
});
useForm({
refineCoreProps: {
liveMode: "auto",
},
});
In this code, liveMode: "auto" means that the form data will be updated automatically whenever a related live event is received. For more information, refer to the Refine's useForm hook (https://refine.dev/docs/packages/react-hook-form/use-form#livemode) documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
