Assuming that you're comfortable with creating a Drupal form, you can create a Drupal form checkbox (technically a Drupal checkboxes element) as easily as this:

# an html checkbox for our drupal form

# the options to display in our checkboxes
$toppings = array(
  'pepperoni' => t('Pepperoni'),
  'black_olives' => t('Black olives'), 
  'veggies' => t('Veggies')
);

# the drupal checkboxes form field definition
$form['pizza'] = array(
  '#title' => t('Pizza Toppings'),
  '#type' => 'checkboxes',
  '#description' => t('Select the pizza toppings you would like.'),
  '#options' => $toppings,
);

The checkbox is specified in this line of code:

  '#type' => 'checkboxes',

This Drupal checkboxes form field definition renders an HTML checkbox field that looks like this:

Note: I originally wrote this tutorial for Drupal 6, and I just confirmed that it works for Drupal 7 as well.

(If you're not comfortable with creating a Drupal module or Drupal form, please see my simple Drupal form example/tutorial.)

You can add even more fields to your Drupal checkbox definition. The fields you can add are defined in the grid at this Drupal Form API reference page.

Adding multiple checkboxes in Drupal-form

$options = array('A', 'B', 'C');
foreach ($themas as $thema) {

        // Initialize array
        $ra = array();

        // Fill up the array with different keys
        $key = $prefix.'_thema_'.$thema->tid.'_fiche';
        $ra[$key]['#type'] = 'checkboxes';
        $ra[$key]['#name'] = $prefix.'_thema_'.$thema->tid.'_opties';
        $ra[$key]['#options'] = $options;
}

正确答案 

I think it's because you're re-initialising $ra in every step of the loop so it will only ever contain one set of checkboxes. Try initialising it outside of the loop:

$options = array('A', 'B', 'C');

// Initialize array
$ra = array();

foreach ($themas as $thema) {
    // Fill up the array with different keys
    $key = $prefix.'_thema_'.$thema->tid.'_fiche';
    $ra[$key]['#type'] = 'checkboxes';
    $ra[$key]['#name'] = $prefix.'_thema_'.$thema->tid.'_opties';
    $ra[$key]['#options'] = $options;
}

$form['some_key'] = $ra;

Also make sure your $prefix string doesn't start with a # symbol or Drupal will consider it a property rather than an element that needs to be rendered.

It was indeed an initializing issue! The value #options got overwritten every time.
