Thanks! Should have read the FAQs first. my apologies.
Just pasting what I did here for those in my situation:
– Installed the JQUERY Widgets WP plugin
– Added jQuery(document).ready(function($) {$(‘#tabs’).tabs();}); in the Custom jQuery Code box in setings
– ticked Tabs in Use this jQuery UI Scripts. Saved
– Inserted HTML as per http://jqueryui.com/tabs/#default
Done.
