Hi Joseph,

T o be honest, I wouldn’t worry about including either hasPopUp or aria-expanded states because, as far as the screenreader is concerned, the text is visible, and there are no changes in display style status.

I may be reading this wrong, but it seems you are trying to describe what is visually happening on the page when, to a screen-reader, nothing is happening.

Massive apologies if I am mis-reading this.

Cheers,

Jeremy.
