Re: Examples for Implementing Accessible Hide/Show Panels

The OAA examples work quite ok actually, though I do not necessarily
agree 100% with the markup.
aria-expanded should be on the buttons that control the display/hide
of their associated panels rather than on the panels themselves.
(keep in mind, if we do this, the name of the button .. in this case
its value property, should not change, it should just be "topic 1" and
aria-expanded should be updated to indicate visibility of the
associated panel).
Also I do not think the focus should move from the button to the panel
it controls, especially not when the content is inline to the button
(comes right after the button, in content order).
You seem to be looking for an accessible accordion pattern (or a
variant thereof).
Simplest example can be found here:

An accordion example can be found e.g. at:
