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.

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:
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:
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.

@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:
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.
