Manual activation example
Apples
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 keyboard tabs.)
Oranges
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.
These things are never about fruit...
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.
