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 can I add a separator to the expanding navigation bar using the dynamic functions?
It seems as though the only way to get a separator into the menu is by defining itbefore hand,
but the website I'm building will require me to reload themenus dinamically,
and I'm losing the ability to put separators on it.
A: You should add items using the following function:
function dm_ext_addItem (menuInd, submenuInd, iParams)
or
function dm_ext_addItemPos (menuInd, submenuInd, iParams, Pos)
Find more info:
http://deluxe-menu.com/functions-info.html
Set the following parameter:
var dm_writeAll=1;
So, you should write:
dm_ext_addItem(0, 4, ["|-", "", "", "", "", "", "", ])
Q: There is the possibility in the dhtml menu bars that an item has access control, that is is visible or not depending of the user?
A: You can use Javascript API and write your own code.
See more info here:
http://deluxe-menu.com/functions-info.html
You can use
dm_ext_changeItem (menuInd, submenuInd, itemInd, iParams)
to disable your items or
dm_ext_changeItemVisibility (menuInd, submenuInd, itemInd, visibility)
to hide your items.Try that.Q: This is probably a really basic question, but I was wondering if your software makes it possible to determine the direction of the drop down menu. In other words, my easy dropdown menu is at the bottom of the page and I want the drop down list to actually go "up," not down. Is that possible with your software?
A: Yes it is possible.
You should use the following easy dropdown menu parameter
var subMenuVAlign="top"; //downward
var subMenuVAlign="bottom"; //upward
var subMenuAlign="left"; //from left to right
var subMenuAlign="right"; //from right to left
