Questions tagged [nested-forms]

A form within another form, often in the ruby-on-rails environment.

This is a Rails gem for conveniently manage multiple nested models in a single form. It does so in an unobtrusive way through jQuery or Prototype.

This gem only works with Rails 3.

Nested forms are when a form is placed within another form, often in the environment.

As of HTML 5, the form element can't be nested. Check section 4.10.18, "Association of controls and forms" for more information.

The platform can also handle nested forms, like the example below:

<div class="form">
    <?php $this->renderPartial('_form', array('form'=>$form)); ?>
    <?php echo $form['user']; ?>
    <?php echo $form['profile']; ?>
    <?php echo $form['subformbuttons']; ?>
</div>

Check the section for general questions and details about forms.
