you can create a link on your page to a show a specific tab on a page by using the target url parameter in the link where the value of the target is equivalent to the tab title.
eg a link to the url http://yoursite.com/contact/?target=email-addresses will open with the ’email addresses’ tab open if there is one.
If you also want the page to scroll to the tabgroup so it is visible onscreen without scrolling when the link is clicked, you can also be able to specify an anchor in the link. The id of each tab follows a simple pattern using the number of the tabgroup and the number of the tab: eg #tablist2-tab3 – you can view the page source to confirm the values to use. Alternatively add your own named anchor before the tab group and link to that.
