Disabled and Invisible Tabs in TabPanel

The TabPanel control allows the user to disable or hide individual tabs using the isDisabled and isVisible properties respectively. Invisible and disabled tabs cannot be selected by the user.

The code example below enables/disables the Europe tab and hides/unhides the Oceania tab based on the checkbox selection as depicted in the image above:
