I dont think theyve made a program that outputs items which cannot be used by those with disabilities.

The program allows the user to select whether or not to apply sub menus to a navbar so it is up to the site designer!

Does anyone know where web-designers actually stand with this?

I had a look at a text reader from
helpread.com. The reader copied all text from the web page http://helpread.com/ and inserted it into the reader and began reading the text.

It didnt copy the text displayed on the menus within the page.

Even if readers do copy the text of a navigation bar then would it be able to copy text of objects in the page which are dynamically created?

I suppose it would be necessary to add text links to page in addition to having menus such as those within menu maker or from other menu providers.
