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: Is it possible to centere mouse over drop down menu?
A: Check that you set relative position for the menu:
var absolutePos=0;
var posX="0px";
var posY="0px";
Place your menu in DIV or TABLE with center alignment.
Q: Hi, I was wondering if there is a way to leave a main navigation item highlighted when in that section. For example if I clicked on "Contact Us" and when I am on the contact us page, the "Contact us" navigation would still be highlighted. I appreciate any help you might have, thanks!
A: The menu has only two states normal and mouseover. We'll try to add the pressed state in the future.
You can set a pressed item using Javascript API:
function dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion)
Sets a current pressed item.
menuInd - index of a menu on a page, >= 0.
submenuInd - index of a submenu, >= 0.
itemInd - index of an item, >=0.
recursion = true/false - highlight parent items.
But notice, to use dm_ext_setPressedItem() you should know ID of selected item and subitem.You can't get this ID after you reload your page. That is why you should write your own code on PHP.
Q: I have another question regarding the popup window. I need to use an iframe within the popup window. Is there any way I can close the onmouseover popup from the page loaded within the iframe? Something like "parent.document.getElementById('windowid').hide();". Any help would be appreciated.
A: You can close the onmouseover popup using the following function:document.getElementById('win').hide();
Unfortunately it won't work if you use iframe as window content.
You open another page in the popup (in Iframe) so you cannot accessdocument.getElementById('win').hide();
element which is situated on the first page.
When you use text or object_id as window content the content of the popup will be situatedon the same page so you can access document.getElementById('win') element and hide it.
There is a workaround.
Use text as content type and add the following code inside popup:
<a onclick="document.getElementById('win').hide();">...</a> <iframe></iframe>
Your link will work in that case.
