Using the tab control in semantic-ui

I was also looking into this. It seems the tab plugin is not yet "released" or documented yet. See https://github.com/Semantic-Org/Semantic-UI/issues/209.

There's a good blog article covering the tabs here: http://patrickgawron.com/wp/semantic-ui/

Your main problem was that you need to use javascript to wire up the tabs. I added the dependencies and this code to invoke the tab plugin:

$(document).ready(function(){
    $('.demo.menu .item').tab();
});

Update:

If you pass { history: false } to the tab function, then you don't need jquery.address.
