We have an in-house web-based data management system that relies pretty heavily on a tree structure displayed as part of most pages that get displayed. Essentially, as I understand it, it's a DHTML-type visual organization that looks much like a tree in, say, Windows Explorer. However, it's really hard for me, as a blind person, to tell what's going on with this tree. There are images shown to indicate if a node is expanded or collapsed. There are images next to the text of each node label, and these images aren't described in a speech-friendly way. I've suggested to the developer that they could put Alt text on the nodes to indicate expanded/collapsed states. That would help, but what bothers me is that, as you expand and collapse nodes and then navigate downward through the tree, there's no way of telling when you reach the end of a sub-branch and move on to a new node that could be one or more levels higher up in the hierarchy of the tree. Using a screen reader in Windows Explorer, you generally hear "Level 0", "Level 1", etc. to tell you how deeply burrowed you are. Does anybody know of a web site where a speech-friendly tree structure can be found? I'd like to point our developer at such a site. I'm also curious if there are readily available "tool kits" that one might use to easily build accessible trees. I should mention that the tree is used primarily for navigation--to move you to a new page of information. The tree doesn't actually place the page content in the nodes of the tree themselves. Thanks a lot, Jerry
