Ok, I've gone about as far as I can to use this code for standard
navigation. It's still not as standard as it should be. So I'm asking for
some help from you guys that know how to code. I'm including below the two
page elements which currently work on:
http://www.accollarts.net/example/example4
The current set up displays only the 'named' topic tree, including sub
topics and all articles. When selecting any article in sub topics, the
navigation changes to only display the sub topic and articles. This is not
what I consider standard navigation.
What needs to occur is the following:
1. main page only displays ALL topics only
a. clicking on topic, displays topic and articles, or
1. if sub topics exist, then only sub topics
a. clicking sub topics displays article links
1. clicking article displays article
2. a link back to the previous sub topic, topic, main page via a "back" link
Note that the description for topics/sub topics, and/or abstract and content
display in the main section of the table for the page. This is way cool!
If anyone could help me with this code, the newbie user community would
greatly appreciate it! As I've said before, once there is a set of standard
navigation code completed, I will be happy to do whatever it takes to give
the code to midgard and hklc so it can be included in their respective
manuals.
If you do respond with code suggestions, PLEASE comment it so the not so
knowledgeable users can make heads or tails out of it ;-)
Thanks in advance!
