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: I am testing it on my website.
I have under the submenu 'Generalites" two links "Presentation" and "Formulaires"
I would like when I click on what ever link on the expandable javascript menu that the visited link stay in a different color and with a different background.
For exemple:
If I click on link Presentation then this link will become in a different color and also its background.
Then If I click on Formulaire the prevous link is reset and the Formulaire link appears in a differemt color and its backgroud. How should I do it ?
A: Deluxe Tree doesn't save a pressed
item as it saves a tree state. It works within 1 page only and if youreload the page you should set a pressed item using Javascript API:
function dtreet_ext_setPressedItem (menuInd, itemID)
Please, see here:
http://deluxe-tree.com/functions-info.html
You can also set
var tsaveState = 1;
More info you can find
http://deluxe-tree.com/data-samples/tree-menuxp-save-state.htm
To expand specific items you should use API function
function dtreet_ext_expandItem (itemID, expand)
Q: Thank you for such an excellent product. I have a question pertaining to the submenu items in your tree-menu line. My menus are 540px wide and contain lots of text with good sized pictures (icons). Can I use an iframe tag inside of the css menu submenu instead of simple text with this icon?
A: You are able to paste any html code within items.
So you can paste a form too.
For example:
var menuItems = [
...
["||<nobr><FORM method=GET action='http://www.google.com/custom'><input name='as_q' value='search
the web' size=15 style='font-size:10'> <INPUT type=hidden name=cof
value='LW:144;L:http://domain.edu/images/sulogo.gif;LH:45;AH:center;GL:0;S:
http://domain.edu;AWFID:e01cb67b8afe383e;'></form></nobr>","",
"images/icons/search.gif", "", "", "", "", "2", "", "", "",],
Q: I updated the files you talked about. I can see the javascript cascading menu on most computers, but not all. I am sorry to ask the same question over but my problem is persisting with some computers.
A: It is not correctly to add # symbol before the top item. This itemwill be hidden.
