States

-
Enabled
The enabled state of a tab is when the user’s cursor is not hovering over it, and the button isn’t disabled. -
Occupied
Only one tab can be occupied at a time. By default, the tab that is on the left is occupied. -
Hover
A tab is in a hover state when the user's cursor is on the tab, but they haven't clicked on it yet. -
Disabled
The tab becomes disabled when its action is blocked by a condition that must be completed first, like changing a field value or waiting for a system response. The disabled state has to be supported by an explanatory tooltip to inform the user why the tab is disabled.
