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: Can your dhtml popup menu work in conjunction with a scroll wheel?
A: You cannot scroll submenus using scroll wheel when you set
var smSmartScroll=1;
To scroll your submenu you should move your mouse.
But you can use scroll wheel when you set
var smSmartScroll=0;
Q: Hi, I need to know if it is possible to accomplish the following functionalities with your tree-menu library.
1. I need to have two or more trees in the same page
2. I need to have a checkBox in each node and through a JavaScript function be able to add the selected nodes into another tree.
3. I need to eliminate the nodes that has check=true
4. I need to populate on-demand the tree using AJAX
5. I need to implement drag&drop through the use of the mouse events on the tree nodes
6. How would the tree behave with 10000 nodes??
7. I need to have a tree within another element that uses scroll
such as a DIV or SPAN (fixed area). When collapsed or expanded, the area should remain its original size.
A: 1. You can add any number of the menus on the one page.
2, 3, 5. Yes, you can do it. But you should create your own server-side script (for example, php) that will do it. The menu doesn't support such a feature.
4. Unfortunately, you can't use the AJAX-like technology in the Deluxe Tree such as in Deluxe Menu.
6. It is possible that the loading speed can be lower if the menu is very large. But it doesn't take so much time.
Yes, you can notice some delay in IE, but in over browsers it works better.
Deluxe Tree works fast, but 10000 is a large value. Please, try atrial version of Deluxe Tree.
I tried to create large menus on my machine: P4 3GHz, 512RAM WinXP SP2
It takes:
- 1000 items ~ 10 sec
- 2000 items ~ 40 sec
7. You can paste Deluxe Tree into the <table> or <div>.
Q: How do I apply styles to submenu items that are different from the styles of top javascript drop down menu items? For instance, I want to know how to apply background images for the submenus, but not for the menu items. I also want borders around the submenu ITEMS, not just the entire submenu. Here is the link to my page with the menus. The menu I am referring to is the top right hand menu (black with grey).
A: Create Individual Item and Submenu styles and assign it to your submenu items.
var itemStyles = [
["itemHeight=23px","itemBackImage=deluxe-menu.files/btn_black.gif,deluxe-menu.files/btn_cyan.gif","itemBorderWidth=1","itemBorderStyle=solid,groove","itemBorderColor=#2C2C2C,#FF0000"],
];
var menuStyles = [
["menuBackColor=transparent","menuBorderWidth=0","menuBorderStyle=none","itemSpacing=0","itemPadding=0px 0px 0px 10px"],
];
["Home","testlink.html", "", "", "", "", "", "", "", "", "", ],

Assign Individual Items style to all submenu items and Individual Submenu Style for the first item in each submenu.
