Q: You've been helping me with some issues on the Javascript/DHTML Tree Menu system my company has purchased and most issues are resolved, so thank you! One big problem remains though and we can't seem to figure it out, so I hope you can help.
What we want is, when a user enters our site from the index (home) page then clicks on a link and the sub-page opens, for the dhtml menu tree to be open to the section the user is in and viewing. We also DO NOT want the browser to save the state of the menu, since that is inconsistent with where the user is in the site. Note: we do not use the Menu on the home page, is this a problem?
Per your tech support email, I've added the expand code, which works going from the home page to sub-pages. However, it interferes with navigating to other sub-pages once your in the site. The menu doesn't keep the section open, it closes back up. You mentioned the expand code has to be entered on every page....is that so in this instance and if so, that's a maintenance nightmare - does a better way exist for this type of menu?
Then we activated the "save state" option and the menu stays open on the sub-pages, but the expand option doesn't work.
It's like they cancel each other out and you can only have one or the other.
Can I get these two to work together? What do I need to do? Is it better to use the XP-style menu?
A: When user clicks the link, the browser loads a new page and the script re-create the dhtml menu tree.
If you want to open the needed section automatically on load you can use the following:
1. Save the state to cookies
2. Use frames
3. Put the special script on each page of site that will open appropriate section.

Q: We are testing you menu in our application. It is being used in cross frame mode. It works very nicely except a couple issues.
The main one is after loading a new page in the sub menus window when I go back to the main menu to select another option but on the initial mouse over it takes several seconds for the menu to come up. Once the delay of loading the initial submenu is over it loads all others very quickly until a new page is loaded again. Is there a way to optimize the menu to reduce this load time? I have already set dm_writeAll=0 but that only increased the speed of the initial display of the main menu.
And the other question is does the dmObjectsCheck option work in cross frame mode? I have it set =1 and the submenus still underneath objects (such as select list) which have a higher z order.
A: Try to do the following:
move all <script> calls into <head>, but delete dm_initFrame()function from data .js file -- move them instead of files calls, i.e.:
<head>
<script src=data.js>
...
</head>
...
<div><script>dm_initFrame("frmSet", 1, 2, 1); </script></div>
It this case data will be loaded when <head> will load, but after thatmenus must be shown quickly.
Let me know about results.
JavaScript Tree Menu overlap select objects in cross-frame mode.
Q: I've finally got it working and it looks good. So thanks. But... unfortunally there's still a small problem wich occured after I got everything else working: No matter if I set the parmeter " var texpanded" to '1' or '0' it expands by default tree menu javascript. Why?
I also have another question I forgot to ask you about earlier: Originally I only had the data.js file but in the non-profit zip file you gave me there was no "data.js" file, only "data-tree.js". Wich one will the script use? Do I need both? The javascript call I put where I want the menu to appear calls for "DATA. js". So what good does the "data-TREE.js" file do?
I include the "data.js" file if you need to have a look at it. The "data-tree. js" file is identical now that I changed all the " var tmenuItems" at the bottom). (The "menu.html" I guess you can look at yourself by "View source".)
Also, the submenus where I would like to put XP style menus are not finished yet but for now I have the same "tree" script in them. They are under "DART/dartspel.html", and on six artist discographys under MUSIK: Edguy, Katie Melua, Joe Satriani, Michael Schenker, Trans-Siberian Orchestra and Magnus Uggla. This is if you'ld like to see the sub pages where I use other "copys" of Deluxe-tree. (I hope you don't mind that the "Illegal copyright" nag is very small. It's supposed to dissapear anyway with the new Non-profit license).
A: 1) See the structure of your tmenuItems is incorrect now.
You should write:
["->HEM (Klicka f?r meny)","welcome.html", "data.files/hem.gif", "data.files/hem2.gif", "data.files/hem.gif", "Startsidan", "right", "", ],
Without '|' symbol in the beginning.
2) You should write tleft parameter correctly. Now you have:
//--- Positioning
var tabsolute=1;
var tleft="00px";
var ttop="10px";
Write it in the following way:
var tleft="10px";
3) data-tree.js file is the default tree menu javascript file. There is no need to use it if you already haveyour data.js file.
Q: Just one more question.
I'm making a drop menu sample but I want the dropdown sub menus to drop up!
ie: the nav bar will actually be at the bottom of the page so when you hover over, I need the sub items to rise up.
Can you force this? I can't seem to find anywhere to do it.
A: You should set the following parameter:
var subMenuVAlign="bottom";
