I wanted to contact you personally instead of using the forums initially in order to ask you a couple of questions that you may be able to help/assist with regarding the wp-dtree plugin.
First, the site in question where we're using it: http://www.simcomedia.com/handbook/
The clients love the tree and its functionality. What they've requested is the following:
1) instead of underlining the document being viewed they'd like it to have a yellow highlight
2) they would like the tree to automatically update when the viewer selects another page using the Next / Previous links (right now the wp-dtree continues to highlight the last item clicked in the tree no matter what page the visitor is on). So, if they did not use the wp-dtree to navigate and used one of the other navigation elements the wp-dtree would recognize the page they are on and open/expand/highlight as necessary.
3) If a category is clicked on in the site's main navigation menu is it possible for the wp-dtree to recognize and expand that category accordingly?
Item #1 is i'm assuming a matter of CSS which I can seek out and modify on my own. #'s 2 and 3 are a bit more tricky. Please provide your comments/thoughts on these and what it would take to accomplish. Thank you for your time.
