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.
Q: I have a problem...
On some computers running IE the menu appears and works correctly, on others it doesn't appear.
There is only a line that says JavaScript Menu by Deluxe-Menu.com.
Both of these computers have the same version of IE running. I have reset the security levels back to default levels on both. Still the menu doesn't appear.
For all practical purposes both copies of IE are the same.
A: You should change your security settings in IE to allow Javascript onpages you load. In other case you can't see a dynamic page content.
There is no way to enable these preferences automatically, in othercase there are no reasons to create security preferences.
You can also use Deluxe Tuner application that allows you to generate additional html code for search engine that can't parse Javascript. So, you can use menu links on browsers that doesn't have Javascript support enabled.
Q: I am using the tree menu script in a frameset, and I would like for the selected menu branch to stay highlighted after the user moves the mouse to another window(where the menu brings up a new page),just so the user knows where he/she is.
Is that possible?
A: But if you open links in the another frame (window) the initial frame with your menu isnot reloaded, so the clicked item will be highlighted.
You should set the following parameters:
var ttoggleMode=1;
var tpressedFontColor="#AAAAAA";
You can also set the following parameter to save menu state:
var tsaveState=1;
var tsavePrefix="menu1";
If you install the menu without frames. On your pages you should call the following function/functions to expand/highlight items, for example:
<script>
dtreet_ext_expandItem (dtreet_ext_getItemIDByIndex (0, 0), 1);
dtreet_ext_setPressedItem (0, dtreet_ext_getItemIDByIndex (0, 1));
</script>

A: Menu has data.js (by default) data file with menu parameters, itemsand styles and 9 engine files.
You should only call two .js files on your html page.
