Select 2

Integrates Drupal autocomplete and select fields with the Select2 jQuery library.

After installing Select2 module you can attach Select2 plugin for all selects form elements (on front-end pages and admin pages, if needed) by defining settings on Select2 module config page, you can also define exludion rules for disabling Select2 plugin attaching for some elements by:

• ID,
• CSS classes,
• jQuery selector rules.

For attaching Select2 plugin to form element by Forms API you must define #select2 attribute in element array.

'products_categories' => array(
  '#title' => t('Element title'),
  '#type'     => 'select',
  '#options' => array(),
  '#empty_option' => t('Select element'),
  '#multiple'     => 1,
  '#select2' => array(),
),

Code abowe will atach Select2 plugin for select element with default properties values, in '#select2' array you can define all properties from Select2 documentation, that accepts non-function value (string, int, object etc):

...
'#select2' => array(
  'width' => '150',
  'placeholder' => 'Placeholder text',
  'allowClear'   => TRUE,
  ...
),
...

Also you can individually enable Select2 attaching for fields by setting options in "SELECT2 INTEGRATION SETTINGS" fieldset (if it available for current field) on field configuration page.
