Important changes since 1.0.4

To be more consistent with Nova's other fields, the order of the parameters has changed to become:

NestedForm::make($name, $viaRelationship = null, $class = null),

For instance, this:


Is now the same as:

NestedForm::make('Posts', 'posts', Post::class),

Also, translations are now available in your nested field! You just need to add this key in you language file:

"Add a new :resourceSingularName": "Ajouter un(e) :resourceSingularName"


composer require yassi/nova-nested-form

Attach a new relationship form to a resource

Simply add a NestedForm into your fields. The first parameter must be an existing NovaResource class and the second parameter (optional) must be an existing HasOneOrMany relationship in your model.

namespace App\Nova;

use Laravel\Nova\Fields\ID;
use Illuminate\Http\Request;
use Laravel\Nova\Fields\Text;
use Laravel\Nova\Fields\Gravatar;
use Laravel\Nova\Fields\Password;
// Add use statement here.
use Yassi\NestedForm\NestedForm;

class User extends Resource
    public function fields(Request $request)
        return [


                ->rules('required', 'max:255'),

                ->rules('required', 'email', 'max:254')

                ->creationRules('required', 'string', 'min:6')
                ->updateRules('nullable', 'string', 'min:6'),

            // Add NestedForm here.

You can also nest your relationship forms by adding another NestedForm into the fields of your App\Nova\Post.

NEW: Add a callback before and/or after your relationships have been updated

For instance, if you have to modify a value on the request before the nested form is filled or trigger an event after all relations have been set, you can now simply use this:

->beforeFill(function ($request, $model, $attribute, $requestAttribute) {
    $request->merge(['key' => 'value']);
    // or
    if (!$model->hasSomeProperty) {
        throw new \Exception('You cannot do this.');
->afterFill(function ($request, $model, $attribute, $requestAttribute, $touched) {
    $touched->each(function ($model) {
        if ($model->wasRecentlyCreated) {
            // do something

Add a minimum or a maximum number of children

For instance, if you want every user to have at least 3 posts and at most 5 posts, simply use:


When creating a new user, 3 blank posts will be displayed. If you reach the maximum number of posts, the "Add a new post" button will disappear.

Set the default open/collapse behavior

If you want the nested forms to be opened by default, simply use:


You can also decide to open only the first nested form by using:

NestedForm::make('Posts')->open('only first'),

Modify the default heading

You can modify the default heading using the heading() method. You can use wildcards to add dynamic content to your label such as '{{id}}', '{{index}}' or any attribute present in the form.

NestedForm::make('Posts')->heading('{{index}} // Post - {{title}}'),

Modify the index separator

You can modify the default index separator using the separator() method when you have nested forms (e.g. 1. Post, 1.1. Comment, 1.1.1. Like).
