I don't think you need any ARIA markup for this. We have tested this type of
functionality with screen reader users several times and they have always
been able to understand what is happening. The article you mentioned
acknowledges that it is necessary for the user to have this understanding.
If they don't, then the ARIA won't help them. If they do, our experience
suggests that they don't need the ARIA.

Subject: [WebAIM] WAI ARIA help.. select boxes that are populated via AJAX

Hi,

I am still a newbie to WAI-ARIA and wondering if anyone can help me with the
following:

We are updating our search functionality on our live site and will be
calling data via AJAX. in the following way:

When a user comes to a search page, there will be two or three select boxes
with only the first select input be enabled.

1. The user picks an entry in the first select box.
2. This enables the second box and populates it via AJAX based on the
selection in the first box.
3. The third box is Optional, but it will be populated based on the first
and second selection via AJAX

I understand from the backend developers, they are going use an onChange
event to make the changes

For accessibility, do we need to add WAI-ARIA live regions to the <select
input?
I found this online. Would this be an answer for what I need?

Can someone explain or point me to good references with good set of demos
or samples?

Thank you
