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 try to fix the height of the submenu "Zone Climatiques" to 400px but I didn't find the way to do this. It worked by setting var smHeight=400px but that setting set all submenus. I would like set only the height of "Zone climatiques" submenu.
Thanks for your help.
A: You should create Individual Style
var menuStyles = [
["menuBackColor=transparent","menuBorderWidth=0","itemSpacing=1","itemPadding=0px 5px 0px 5px"],
["smHeight=400px"],
];
and assign it to the first item in submenu
["3101 - Ste-Anne-Des-Monts","ProcessClimaticZone/edit.do?id=3101,2003-11-13", , , , , ,"1","stationSubMenu.htm?climaticZoneId=3101,2003-11-13",],
Q: Compliments on your product, I particularly enjoy the complete set of gui and java, that allows for the quick changes.
After a couple of months of using the trial, I have now purchased it and installed the license.
My question however regards the performance of the menu. Using firebug I note that my deluxe menu .js are the performance bottlenecks, It appears as if they are not being cached and it appears that collecting them is taking longer then the other .js files. What can I do to optimize the load time of the javascript multi level menu and prevent, reloading it from the server with every page reload. The apache has set the expiry correct I believe, as I understand from the header.
A: You can try to use AJAX technology.
AJAX-like technology: data for submenus can be loaded "on-the-fly" from the server.
New parameter:
var tajax = 0/1; - disables/enables AJAX-like support
Current syntax for item parameters ( var tmenuItems):
[text, link, iconNormal, iconOver, iconExpanded, tip, target, itemStyleInd, itemXPStyleInd, jsFileName]
Where jsFileName - .js filename on the server with submenu items ( var tmenuItems).
Q: I am trying to use Delux-menu for our project, I am not able to use dynamic features of drop down menu script. I will send the html file, where I am calling the java script.
I am getting the error dm_menu[mInd] has no properties.
A: You have one menu in your example, but you write:
function hide(vis) {
dm_ext_changeItemVisibility(1, 0, 2, vis);
That is mean that you want to hide item in the second drop down menu script.
You should write:
function hide(vis) {
dm_ext_changeItemVisibility(0, 0, 2, vis);
