What is the best way to dynamically insert an object into a field name in react-final-form?

When using the react-final-form component, you can expect the following result:

<Field
   name="answers[0].name"
   component="input"
   type="radio"
   value="0"
/>


{ answers: [ { name: 'value' } ] } 

Want to add another property to your field? Here's how to do it:

{ answers: [ { name: 'user input value will here', other: 'my custom data' } ] } 

According to final-form, there are 4 ways to name your field component: https://i.stack.imgur.com/moGJA.jpg

Answer №1

To automatically fill in the form with predefined data, you can utilize the initialValues property.

<Form
    onSubmit={onSubmit}
    initialValues={{
        entries: [ { custom: 'your unique information' } ]
    }}
>
    <Field
        name="entries[0].title"
        component="input"
        type="text"
    />
</Form>
