I have a form with three form elements:
'#type' => 'radios'element having two options (Yes or No),
'#type' => 'submit'&
'#type' => 'checkbox'
When the user lands on the form page, he should only see the
radios element first and can see the
submit elements only if he selects an option from
Is there a Drupal way to do this using the Form API?
