This is a very easy way to add a Tree View (like the VB Control) in your html page. With 1 function, add TreeViews with or without checkboxs and links. If you like it, vote for it ! Simon

Good code; even if it doesn't work with NS, it still degrades gracefully. It doesn't expand/collapse, but atleast allows the user to see all nodes.

And BTW, calculate 12% of the annual eCommerce business in billions, and then tell me it doesn't account for much.

Good code!
Looking for a variation possibly....
Is it possible for a certain page to have one of the trees automatically expanded? Example: If I were to pull up a page that was the "Development Sites" page and I would want just that tree to be expanded, but the others not, is there a dynamic way to do that? Just curious. Gracious for any help.

Simon,

This is good code, regardless of which browser you are using. I would hope that I speak for the majority, that you are not liable for restrictions imposed by Netscape.

I like how you test for IE, and if not, the tree is displayed in the expanded format. Great Job!

I've edit my code so now you can set the default display (open/close) for each section of the Tree... like Brian ask for.

Great Code! This really helped me out with a project. I'm using the tree's open position for my Netscape users. Thank you so much for putting this out..very user friendly..

Execellent example. Any ideas about using this code with recursion?
(If this comment was disrespectful, please report it.)

7/17/2001 3:15:45 PM: morganrt

Great Code!
I'm embarassed to say that while I can get the example 'TreeView.asp' to display with no problems, when I replaced the links with links of my own to test it, the tree displays differently.
Now the parent 'Exemple1' is displayed, but the parents 'Example2' and 'Development' remain closed until you click on 'Exemple1'.
Why are the two other seperate parents now under the first?
I don't blame Simon's code, just wondering what I did..?
Thanks

Great Stuff,
I don't have much experience in Web programming so far, but this is the first example on the web (and I found quite a few), which allows you to easily change a bit... Thanks Simon

Clear and nice! - a lovely Treeview. Won´t work in Netscape or Opera since they don´t understand the 'block' style. With Opera I expect they´ll fix that shortly. You have to be careful how you place those 'Writehead' and -foots tho, otherwise the

s don´t get closed and the Treeview 'swallows' up all following menus. I have linked it to a database and will post a recursive, non depth limited version soon...when I have translated my comments from german into english, that is :-)

Excellent! Exactly what I was looking for. I have updated the code so that it is datbabase driven and have created a user interface in VB to build the tree a whole lot easier. Will be posting it soon.

There is one little glitch though. I have the menu building in a left frame. When you expand the nodes and go out past the size of the frame, the text wraps instead of automatically showing the scroll bar. Any ideas on how to fix this? Have tried setting 'scrolling' to yes on the frame but this doesn't do the trick.

I fixed the wrapping issue. Found the <NOBR> HTML tag and used that. Had to place the opening tag before the area where the level is checked and the ending tag after the title of the node is written. -David

5/23/2002 1:58:44 PM: Dan

Excellent idea.Is there a problem with the depth of the levels? I seem to have scripting errors using levels above 5. It might just be my code though. is there a problem with using very very large trees (mine has approx 2500 nodes)?
Any help would be gratefully appreciated.

Thanks for the nice code
