        <ul>
            <li><a href="#tabs-1">first</a></li>
            <li><a href="#tabs-2">second</a></li>

        </ul>
        <div id="tabs-1">
        ...

Answer 1

Disable a tab. The selected tab cannot be disabled. To disable more than one tab at once use:

$('#example').tabs("option","disabled", [1, 2, 3]);

The second argument is the zero-based index of the tab to be disabled. Instead of an index, the href of the tab may be passed.
