Subject: Seeking selected link in Carousel examples
No previous message | Next message →

I remember a few presenters at CSUN describing how their carousels that used dots for navigation were coded. They were marked up as tabs, even though visually they look nothing like tabs. I believe ARIA was part of the mix.

I was doing some research for one of our front end developers to see what I could learn about ARIA for defining a selected state for a list item. I learned that aria-selected doesn't apply to links or list items.

Does this mean that there is no way to code a selected state for a list of dots that are also links? Would a mix of aria-controls and aria-label make this any easier? I still don't see a way to indicate something is selected using ARIA.

Seems like the only option is to dynamically include "you are here" or "selected" text to the image's alt text. Simply not linking the selected item doesn't seem sufficient since it then becomes a non-focusable element.

Any and all tips are most welcome.


Thanks,

Can you send through the markup for one of the actionable dots?

The w3c aria working group is aware of this issue and is anticipating on having an aria property in aria 1.1 specification to solve this problem

This is a long-discussed problem actually.
You would have to map any link (or other underlying focusable element)
as a tab before you can use aria-selected.
See for instance:
http://www.romaingervois.fr/implementations/en/carousel.html

You could map them as buttons and then use aria-pressed="true" on the
selected one, but that really would be presenting the user with
something very different from what you are displaying.

You could use role="presentation" on the currently active one. It
would still remain focusable but would not be announced as a
link/button/tab (whatever the basetype is that you use), so that way
it would be different from the rest. This might be ok if you visibly
mae the active dot/link look like it is not a link or if you made it
look disabled you could use aria-disabled for the equivalent
programmatic distinction.
Then there is always adding off-screen hidden text of course to the active link.

We do need an aria attribute that indicates active or selected that
can be used on any focusable, even possibly on non-focusable element
in a set of elements.
Maybe in the next version of the ARIA spec, who knows.

Thanks for the suggestions everyone. It's comforting to hear that I'm not
alone and this is a known issue.

Bryan, I'm grabbing the code and sending to you off this list, if that's
OK.

These remind me of the page indicators on iOS. For example, VoiceOver announces "page 1 of 7, adjustable, swipe up or down to adjust."

It think it makes more sense to treat the dots as one control with different values rather than separate controls one of which is selected. Perhaps an ARIA slider is an equivalent.
