I'm trying to add a styling to the select form elements in my Drupal form using jQuery UI. I'm using Drupal 7 so the usual way to add jQuery UI would be something like this:

 drupal_add_library('system', 'ui.accordion');
 drupal_add_js('jQuery(document).ready(function(){jQuery("#accordion").accordion();});', 'inline');

However, when I try to add an effect that isn't bundled with Drupal 7 core, like this one, that approach doesn't work. Has anyone come across this problem before, and if so, is there a "standard" Drupal way of solving this?

I think the 'Drupal' way would be to implement hook_library() to add the new element to the system:

function MYMODULE_library() {
  $libraries['ui.selectmenu'] = array(
    'title' => 'jQuery UI: Selectmenu', 
    'website' => 'http://filamentgroup.com/lab/jquery_ui_selectmenu_an_aria_accessible_plugin_for_styling_a_html_select/', 
    'version' => '1.8.7', 
    'js' => array(
      drupal_get_path('module', 'MYMODULE') . '/jquery.ui.selectmenu.min.js' => array(),
    'dependencies' => array(
      array('system', 'ui.widget')

  return $libraries;

And then add it to your pages using drupal_add_library():

drupal_add_library('MYMODULE', 'ui.selectmenu');

Doing it this way ensures that all the necessary core UI files are included in the page automatically, and allows you to add the widget with a single line of code any time you want to.

  • Thanks for your reply Clive. I did that - but also added the css file in hook_library as 'css' => array( drupal_get_path('module', 'planb') . '/css/jquery.ui.selectmenu.css' => array(), ),. I then called the line: $('select').selectmenu(); from one of the scripts that runs on that page. However, I can see no change in the select boxes. The library has definitely been added, as confirmed by a call to drupal_get_library, however I must still be doing something wrong.

    Is your code wrapped in a $(document).ready()?

  • Ah. Yep, that did it. Should've thought of that earlier! Thanks!

You would have to download the .js file and put it on your server. Then reference it this way:

drupal_add_js(drupal_get_path('theme', 'YOUR_THEME_NAME'). '/js/jquery.ui.selectmenu.js');

Don't use drupal_add_library

  • Hi there Brian. Thanks for the reply. Unfortunately that didn't work - I tried adding the CSS file also to no avail. Thanks for the reply though! I'll keep searching and trying.

  • You added it to the right place (your js directory in your themes directory) and changed 'YOUR_THEME_NAME' to your actual theme name correct? If you view source is the select menu js file being loaded? Are there errors in your console? Mar 20, 2012 at 20:44
