Laravel form builder : Child form

You can add one form as a child in another form. This will render all fields from that child form and wrap them in name provided:

<?php
class PostForm
{
    public function buildForm()
    {
        $this
            ->add('title', 'text')
            ->add('body', 'textarea');
    }
}

class GenderForm
{
    public function buildForm()
    {
        $this
            ->add('gender', 'select', [
                'choices' => $this->getData('genders')
            ]);
    }
}

class SongForm extends Form
{
    public function buildForm()
    {
        $this
            ->add('name', 'text')
            ->add('gender', 'form', [
                'class' => 'App\Forms\GenderForm',
                'formOptions' => []
                // Passed to gender form as data,
                'data' => ['genders' => ['m' => 'Male', 'f' => 'Female']]
            ])
            ->add('post', 'form', [
                'class' => $this->formBuilder->create('App\Forms\PostForm')
            ])
            ->add('lyrics', 'textarea');
    }
}

This renders:

    <div class="form-group">
        <label for="name" class="control-label">name</label>
        <input type="text" name="name" id="name">
    </div>
    <div class="form-group">
        <label for="gender[gender]" class="control-label">Gender</label>
        <select id="gender[gender]" name="gender[gender]">
            <option value="m">Male</option>
            <option value="f">Female</option>
        </select>
    </div>
    <div class="form-group">
        <label for="post[title]" class="control-label">Title</label>
        <input type="text" name="post[title]" id="post[title]">
    </div>
    <div class="form-group">
        <label for="post[body]" class="control-label">Body</label>
        <textarea id="post[body]" name="post[body]"></textarea>
    </div>

Beside inherited, there are some additional options available:

class (String Form) (Default: null) - Full path to the Form class or Form instance.
formOptions (Array) (Default: []) - Options that will be passed to the Form if class passed as string
data (Array) (Default: []) - Data to be added to the form

Each of these represent the parameters for the FormBuilder::create() method:

<?php
FormBuilder::create($class, $formOptions, $data);
