Can you disable tabs in Bootstrap?

As of 2.1, from bootstrap documentation at http://twitter.github.com/bootstrap/components.html#navs, you can.

Disabled state

For any nav component (tabs, pills, or list), add .disabled for gray links and no hover effects. Links will remain clickable, however, unless you remove the href attribute. Alternatively, you could implement custom JavaScript to prevent those clicks.

See https://github.com/twitter/bootstrap/issues/2764 for the feature add discussion.

You could remove the data-toggle="tab" attribute from the tab as it's hooked up using live/delegate events
