jQuery ui isn't loading I'm simply trying to implement the tabs widget on a particular page.  


I have both jquery_update and jquery_plugins modules enabled.
If I go to Administration &gt; Reports &gt; Status report Under jQuery Update, I see jQuery 1.10.2 and jQuery UI 1.10.2 are both green and showing as loaded.
If I type jQuery.fn.jquery into the console I see "1.10.2"


But the bad news is


If I try to use jQuery("#tabs").tabs();  I get an Uncaught TypeError: undefined is not a function error
If I enter any of the following "jQuery.fn.ui","jQuery.ui", "$.fn.ui", "$.ui" into the console:  I get undefined
Having this in my template.php:


:

 function my_theme_preprocess_page(&amp;$vars){
   drupal_add_library('jquery_plugin', 'tabs.min.js');
 }


does nothing.


And finally, checking the heading of the rendered page, I see a call to Google CDN to the minified version of jQuery 1.10.2, but don't see any similar call to grab the jQuery UI library.  


Working with Drupal and jQuery is such a nightmare, what else can I check, do, change, to get this working?
In your theme_preprocess_page function use this

drupal_add_library('system', 'ui.tabs');


Here is a list of all the libraries for 'system' https://api.drupal.org/api/drupal/modules%21system%21system.module/function/system_library/7
