Q: Is there a way to make the vertical drop down menu dhtml not reset after a link is clicked. Now every time I click a link in the tree menu it takes me to the linked page but all the menus re-expand.
A: When user clicks the link, the browser loads a new page and the script re-create the vertical drop down menu dhtml.
If you want to open the needed section automatically on load you can use the following:
1. Save the state to cookies
var tsaveState=0;
2. Use frames
3. Put the special script on each page of site that will open appropriate section.
(dtreet_ext_expandItem)

Q: The menu maps to the width size of the longest menu item on the list, can you tell me how I can restrict this, and have a fixed menu size.
A: Unfortunately it is really so.
You can try to wrap your text.
You should set the following parameter:
var noWrap = 0;
or use <br> tags within menuItems.
Q: > You should call the following function:
> dtreet_ext_getItemIDByIndex (0, 12)
> where 12 - is index of the item.
How would I know that 12 is the index of the item? How is itemInd different from its itemID? I assume the menuInd is always 0 for the first menu (or only in my case) menu on a page?
A: Yes, menuInd is the number of the menu on your page (in your casemenuInd=0).
itemInd is the number of the item in your menuItems, for example:
var tmenuItems =
[
["Home", "http://deluxe-tree.com", "icon1_t.gif", "icon1_to.gif","", "Home Page Tip","_blank"],//itemInd=0
["<img src='data_files/images/sep.gif' width=113 height=1>"],//itemInd=1
["+What's New<br><span id='letter'>This is pretty cool. I need to buy this deluxe menu</span>", "", "icon2_t.gif", "icon2_to.gif", "", "Product Info Tip"],//itemInd=2
["|What's New", "testlink.htm", ""], //itemInd=3
["|Features", "testlink.htm", ""], //itemInd=4
["|Installation", "testlink.htm", ""], //itemInd=5
["|Functions", "testlink.htm", ""], //itemInd=6
["|Supported Browsers", "testlink.htm", ""], //itemInd=7
["Samples", "", "icon3_t.gif", "icon3_to.gif", "", "Samples Tip"], //itemInd=8
["|Sample 1", "testlink.htm", ""], //itemInd=9
["|Sample 2", "testlink.htm", ""], //itemInd=10
["|Sample 3", "", ""], //itemInd=11
["||New Sample 1", "testlink.htm", ""],//itemInd=12
["||New Sample 2", "testlink.htm", ""],//itemInd=13
Q: I am having some difficulty dynamically adding items to a tree javascript and menu.
I have a menu with one "root" item. I see the use of the "+" symbol within the item name. I do not see any documentation regarding this symbol, only "|". Can you explain?
If I have one menu with this one "root" node, how would I add an subitem to this root node?
Here is my code so far, but the inserted items appear to be at the same level as the root node.
var rootItem = dtreet_ext_getItemIDByIndex ( 0,0 );
var menuItem = new Array(10);
for ( var i = 0; i < producers.length; i++ )
{
var producer = producers[ i ];
menuItem[0] = producer.name;
dtreet_ext_insertItem ( 0, 0, i + 1, menuItem );
A: See dtreet_ext_insertItem () function has the following parameters:
function dtreet_ext_insertItem (menuInd, parentItemID, itemInd, itemParams)
Creates a new item and inserts it into a specified position.
menuInd - index of a javascript and menu on a page, >= 0.
parentItemID - ID property of an item.<, >= 0.
itemInd - index of a new item within the javascript and menu, >= 0.
itemParams - item parameters.
Notice that parentItemID is the Id property of the parent item (notindex). If you want to add top items you should set parentItemID=0.
itemInd - you should use this parameter if you want to add item in thespecific place, for example set itemInd=5 if you want to add itembefore the existing item with itemInd=5.
If you set itemInd=null the new item will be added at the end of this submenu and its index will be added automatically.
