Checkboxes

Provides a form element for a set of checkboxes.

Properties:

• #options: An associative array whose keys are the values returned for each checkbox, and whose values are the labels next to each checkbox. The #options array cannot have a 0 key, as it would not be possible to discern checked and unchecked states.

Usage example:

$form['high_school']['tests_taken'] = array(
  '#type' => 'checkboxes',
  '#options' => array('SAT' => $this->t('SAT'), 'ACT' => $this->t('ACT')),
  '#title' => $this->t('What standardized tests did you take?'),
  ...
);
