RE: Regarding selected cells within a static data table

Selected is specifically a widget state; it has nothing to do with static
elements. That is how it is represented in accessibility APIs. 

 

What does it mean to say a cell is selected in a static table? How do you
change selection if the table is static? I think there is a confusion of
concepts here.

 

We should not consider supporting aria-selected on elements that are not
selectable.

 

Perhaps some more detail about the scenario could shed some light on how to
represent the UI for assistive technologies.

Can I clarify 1 point. Is this intended to allow a user to make a selection
or is it only intended to indicate what is selected (as the result of
another process)

Subject: Regarding selected cells within a static data table 

 

Hi,
This came up last week, and seems to indicate a missing area in what we have
available in either aria-current or aria-selected, but I'm not sure which.

The scenario is a static data table where a series of situations are
possible, (1) all cells in a column are highlighted as being selected, (2)
all cells in a row are highlighted as being selected, or (3) any number of
random cells within the data table are highlighted as being selected.

I was asked if aria-current could be used for this, but this does not
actually fit because this only deals with one current item in a collection.

Similarly, the aria-selected attribute won't work because it is not
supported on role="cell".

Also, it is invalid to add role="grid" to the construct just to expose
aria-selected because this is a static data table and is not an interactive
widget.

So, since nothing is available to deal with this, it seems that it should be
either handled by aria-current or aria-selected, even though at present it
does not.

Would it be agreeable to extend aria-selected to be supported on
role="cell"?

Or, would adding a token to aria-current be more agreeable such as
aria-current="selected"?

What are your thoughts?

Thanks,
Bryan
