Q: Is it possible to make on top of the javascript expandable tree 2 extra buttons:
* Expand all
* Collapse all
Which command do I use???
A: Tree Menu doesn't have such a feature now.
You can write your own function based on the following API functions:
function dtreet_ext_showItem (itemID, visibility)
function dtreet_ext_expandItem (itemID, expand)
Q: Some menu entries may be disabled and clicking on them should produce predefined javascript alert message?
A: To create disabled items you should set "_" symbol in the targetparameter of the menuItems.
If the target is "_" the item is disabled.
You can assign a font color for all disabled items using the following menu parameter:
var fontColorDisabled = "#AAAAAA";
You can write a javascript code instead of an item link:
["item text", "javascript:alert('Hello World')", , , ,"_",]
That's all.
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 have small problems with your javascript menu system.
#1. I am creating a multi-level menu, am I limited to a gird format or can every item have a variable column width?
#2. With submenus, I want to have the submenu be the same width as the parent cell, is there a simple command for this, or do I have to guess the column widths until it fits correctly?
#3. In those same submenus, I have items that are longer than the parent, is there a word wrap or a way to define a break, rather than having the scroll feature?
A: 1) You should use Individual Item Styles.
For example:
var itemStyles = [
["itemWidth=120","itemBorderWidth=1","itemBorderStyle=solid,solid","itemBackColor=#ACF88B,#ACF88B","itemBorderColor=#329309,#329309"], //style0
["itemWidth=100","itemBorderWidth=1","itemBorderStyle=solid,solid","itemBackColor=#FFFFFF,#FFFFFF","itemBorderColor=#1B92E9,#1B92E9"], //style1
["itemWidth=130","itemBorderWidth=1","itemBorderStyle=solid,solid","itemBackColor=#FF9684,#FF9684","itemBorderColor=#EC7575,#EC7575"], //style2
["itemWidth=150","itemBorderWidth=1","itemBorderStyle=solid,solid","itemBackColor=#84F9FF,#84F9FF","itemBorderColor=#00B8C1,#00B8C1"], //style3
];
var menuStyles = [
["smColumns=2"], //style0
];
["Home","testlink.htm"],
["Samples","testlink.htm"],
["|Group 1","", , , , , "0", , , ],
["|Group 2","", , , , , "1", , , ],
["|Group 3","", , , , , "2", , , ],
...
[" More Samples","testlink.htm"],
["|Group 1","", , , , , "3", "0", , ],
["|Group 2","", , , , , "1", , , ],
Where "0", "1", "2", "3" - style number in itemStyles.
2) You can also use Individual Item Styles.
var itemStyles = [
["itemWidth=120px"],
];
var menuStyles = [
["smWidth=120px"],
];
["Product Info","", "default.files/icon1.gif", "default.files/icon1o.gif", , , "0", , , ], // itemStyles
["|Features","testlink.html", "default.files/icon2.gif", "default.files/icon2o.gif", , , , "0", , ],
["|Installation","", "default.files/icon2.gif", "default.files/icon2o.gif", , , , , , ], // menuStyles
3) Try to set this parameter:
var noWrap=0;
