No explicit default was set, so per standard functionality
this first tabpanel will be shown by default.
Here's a link just to test keyboard tabbing.
(it's odd talking about tabs, and tabs.)
Bananas
This is an example of a heading being used to populate the
tab's label, while also not removing heading
from the tabpanel. This is done by adding
the value "keep" to data-atabs-heading.
There are two headings here
The tab is getting its label from the
data-atabs-tab-label. The heading is
kept in the tabpanel because it does
not have the data-atabs-heading
attribute.
It wouldn't make much sense
If the contents of a tabpanel contain
additional sub headings, it wouldn't make sense to remove
the initial heading from the tabpanel.
Doing so would create a gap in the heading structure.
Special demo: enabled a disabled tab
There are some cases, e.g. in a multi-step process, where a user completes a task in an exposed tab panel or panels, and then by completion of that task a previously disabled tab becomes enabled.
The following button showcases how that could be implemented for the disabled "Mangos" tab.
Mangos (out of stock)
This text will never be visible, unless the tab is enabled via JS. Please refer to the demo button in the "Oranges" tab for an example how this could be achieved.
