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: How I can write the changed dhtml pull down menu into a database?
A: Unfortunately, we don't have such example.
You may generate a menu from a database or XML using any server-side script, e.g., PHP, ASP, VB, etc.However, these scripts don't work inside of Javascript .js files, so, you should move parameters of a menu from a .js file into an html-page, e.g.:
<!-- Deluxe Tree -->
<noscript><a href="http://deluxe-tree.com">Javascript Tree Menu by Deluxe-Tree.com</a></noscript>
<script type="text/javascript" src="menudir/dtree.js"></script>
<!-- (c) 2006, http://deluxe-tree.com -->
<script type="text/javascript" language="JavaScript1.2">
// and describe parameters of a menu
var parameter1=value1;
var parameter2=value2;
etc.
var tmenuItems = [
// here you generate items using server-side scripts (php, asp, vb, etc.)
];
</script>
The example of the menu working with PHP/MYSQL you can find here:

This example is not for Deluxe Tree menu, but you can create your menu in the same way.
Q: I am using javascript dropdown menu - Deluxe Menu 2.0 and have some problem with the doctype declaration.
Is there any need to classify a certain doctype in order to get the menu working correctly?
If we use the XML declaration (like this: "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">)
the padding and margin settings of the submenus get lost.
Are there any known solution to fix this?
A: Yes, it happens if you don't specify units in "px" for some dropdown menu parameters.
Please, try to write so:
var itemPadding="2px";
Q: Tree menu doesn't display properly in Firefox or IE7. Could you give me advice on how to correct this problem? The menu creates black 'blinds' horizontally across the page. Since IE7 will be rolling out soon I need to get this corrected sometime in the next couple weeks.
A: Try to specify units in "px".
var tmenuWidth = "280px";
It's necessary to specify exact value for Mozilla browsers. It helps to position menus correctly.
