Re: ACTION-1442: Draft spec text for aria-current and aria-currentfor

Is there a sue case for aria-current and aria-selected to be on the same element at the same time?

Could something in practice look like this:

<div role=“xxx” aria-current=“true” aria-selected=“false”>

Can a set of items ever have more than one item with aria-current=“true"?

On items that are multi-selectable there can be more than one item with aria-selected=“true”, this seems to be a potential difference between aria-current and aria-selected use cases, a set can only have one aria-current=“true”.   But then that begs the question of what defines the set of things?

Maybe the first implementation of aria-current should be limited to role=link items and be limited to indicating that this link is the link to the page or state of the current page.

I’ve made a few updates to the draft text based on today’s discussions. I’ve changed the examples to include one that isn’t link based, and have changed the note to use the wiki use case Matt mentioned earlier because I think it’s easier to understand.

Aria-current attribute

Indicates the element that represents the current item within a container or set of related elements.

The aria-current attribute indicates whether an element represents what is current (true), or not current (false). If the aria-current attribute is false or undefined, the aria-current state of an element SHOULD not be exposed by User Agents or assistive technologies.

The aria-current attribute is used when an element within a set of related elements is visually styled to indicate it is the current item in the set. For example it can be used to indicate a link within a set of navigation links, where the link is visually styled to represent the currently displayed page. It could also be used to indicate a link that is visually styled to represent the current step in a process, or an image that is visually highlighted as the current component of a flowchart.

Note:
The aria-current attribute is similar to the aria-selected attribute, but there are important differences. For example, aria-current would be used to identify the link representing the page currently displayed on the wiki, whereas aria-selected would be used to indicate that the link had been selected for an action (such as moving the page to another location.

Characteristics of aria-current
Used in roles: All elements of the base markup.
Value: true/false

Values of aria-current
true: The element is current.
false (default): The element is not current
