Q: Can I choose what items will be expanded or collapsed in the php tree view
when the user first comes to the webpage?
A: You can expand some items by default.
Add '+' sign before items text in that case:
["+Deluxe Tree: XP Style","", "deluxe-tree.files/xpicon1_s.gif", "", "", "XP Title Tip", "", "0", "", "", ],
["|Home","testlink.htm", "deluxe-tree.files/icon1_s.gif", "deluxe-tree.files/icon1_so.gif", "", "Home Page Tip", "", "", "", "data-new.js", ],
"Deluxe Tree: XP Style" item will be expanded by default in that case.
Use var texpanded=1; parameter to expand all menu items by default.
Use function dtreet_ext_expandItem (itemID, expand) API function to expand the specificmenu items dynamically:
http://deluxe-tree.com/functions-info.htmlQ: I downloaded the free trial version and so far it looks like we can do everything. I have a couple questions:
the designer wants it so that when any of the submenu choice are selected, the main main menu in java item should be highlighted when the submenu page is displayed (kind of a breadcrumb). So, is there any way to change the background image of one of the main menu items after the menu loads? I haven't tried running my main menu in java in a webpage yet so I'm not sure if you generate a separate CSS file or put all of the settings into a STYLE= attribute of each tag.
A: The main menu in java has only two states normal and mouseover.
Try to do the following things:
- delete var pressedItem=1; parameter from your data file
- set correct parameter on each page before you call data file, forexample:
<noscript><a href="http://deluxe-menu.com">Javascript Menu by Deluxe-Menu.com</a></noscript>
<script type="text/javascript"> var dmWorkPath = "menudir/";</script>
<script type="text/javascript" src="menudir/dmenu.js"></script>
<script type="text/javascript"> var pressedItem=3;</script>
...
<script type="text/javascript" src="menudir/data.js"></script>
You can also 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: Is there a javascript API for the expandable menu tree to fire an user click event so the browser will load proper page accordingly? I looked around the current APIs from your site and could not find one.
Please advise.
A: You can use dtreet_ext_userClick (itemID) function.

Actually you can use your own Javascript code instead standard links and html code inside item text. For example:
var tmenuItems = [
["text", "javascript:your_code_here"]
];
or
var tmenuitems = [
["<div onClick='urlSubstitution(\'transco/sheet.asp?stype=1\')'>Table of Contents</div>", ""]
];
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>.
