Success Criterion 1.3.1: Info and Relationships: what about inaccessible drop-down menus?

Hi,

Just wondering what your thoughts are on this:

Re: Understanding Success Criterion 1.3.1: Info and Relationships

This success criteria is about ensuring that, 'information and relationships that are implied by visual or auditory formatting are preserved when the presentation format changes.'

So would a drop-down menu that is inaccessible to screen readers (and keyboards users) mean this checkpoint fails?

There's no indication that the checkpoint is designed to include this kind of issue, as it refers to tables, colour, forms with required fields - and the robustness of these - to different presentation.

Clearly the structure of the menu and the relationship between the the top-level link and the sub-links in the pull-down menu does not survive - when the menu is being access by a screen reader. So it should be a fail?

Any thoughts?

Sorry if I'm missing something here.

Thanks,
Jim
