Re: Update tree view examples for review on Monday APG call

Jon,

One thing that has been discussed recently is whether an element with role
treeitem may only have presentational children. And in your example you
have a <li> element with role treeitem and a descendent <a> element with a
href. As far as I can tell, an <a> element with a href is interactive
content. So my interpretation is the <li> element with the role treeitem
does not have only presentational children. What am I not understanding? Is
a <a> element with a href presentational? Or do you not believe that a
element with a role treeitem should not be restricted to only have
presentational children?

Subject: Update tree view examples for review on Monday APG call



Matt, James and Michiel,

Here are the updated tree view examples based on the APG discussion this
week, hopefully can discuss changes on Monday’s call.

https://rawgit.com/jongund/aria-practices/master/examples/treeview/treeview-1.html


https://rawgit.com/jongund/aria-practices/master/examples/treeview/treeview-2.html



The changes include:
1. Adding a description of the example after the title
2. Updating the keyboard support to match authoring practices
3. Added section on synchronization of visual and aria states
4. Added aria-level, aria-setsize and aria-posinset information to examples

Still todo:
1. Using character to navigate visible tree items
2. Using ‘*’ to open all descendant leaves of the current treeitem
