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: When I check my website for accessibility it shows NoAlt on the dhtml drop down menu!.
Where do I add an alt tag in the data file?
A: You should use the fifth parameter in menuItems
[text, link, iconNormal, iconOver, tip, target, itemStyleInd, submenuStyleInd, jsFilename],
For example:
["Home","index.htm", "", "", "Home", "", "", "", "", ],
["|Dr. Copeland's Bio","bio.htm", "", "", "Dr. Copeland's Bio", "", "", "", "", ],
["|Destiny History","history.htm", "", "", "Destiny History", "", "", "", "", ],
["|Contact Destiny","contact.htm", "", "", "Contact Destiny", "", "", "", "", ],
["|Dr. Copeland's Itinerary","itinerary.htm", "", "", "Dr. Copeland's Itinerary", "", "", "", "", ],
Q: I need to know how to have the background in the main items of the dynamic menu transparent, and then the sub-menus a different translucent color.
A: To set transparent background for the menu you should set:
var menuBackColor="transparent";
var itemBackColor=["transparent","transparent"];
and use Individual Item Styles for your submenus:
var itemStyles = [
["itemBackColor=#8EE8E1,#26BBB0"], //style0
["itemBackColor=#F4B7FB,#E65AF5"], //style1
];
var menuItems = [
["Home","testlink.html", "", "", "", "", "", "", "", ],
["Product Info","", "default.files/icon1.gif", "default.files/icon1o.gif", "", "", "", "", "", ],
["|Features","testlink.html", "default.files/icon2.gif", "default.files/icon2o.gif", "", "", "0", "", "", ], //style0

Q: I want to use
function dtreet_ext_userRightClick(itemID) {
alert(itemID[0]); ???
return false;
}
But how do I refer to tmenuItems array using itemID in the javascript?
For example, if I want to pop a link text, should I use alert(itemID[0]))?
It doesn't work.
Please let me know how I refer to the menu.
A: You should use the following function to get item's info:
dtreet_ext_getItemParams (0, itemID);
For example:
<script type="text/javascript">
function dtreet_ext_userRightClick(itemID)
{ var link = [];
link = dtreet_ext_getItemParams (0, itemID);
//Returns item parameters in the array:
// [item_id, index_within_submenu, parentID, level, has_child, child_count, expanded, text, link, target, tip, align, icons, hidden, disabled, visible]
alert(link[7]);
return false;
}
</script>
